Why use iWatermark Pro Over Other Programs

  • iWatermark is less expensive, faster and easier for watermarking than Photoshop because it was designed exclusively for watermarking and the workflow of professional photographers.
  • There are different iWatermark versions made for Mac, Windows, iOS, and Android. iWatermark Pro.
  • Watermark individual photos or batches.
  • Use one watermark or as many as you want simultaneously
  • 11 watermark types. Other apps have only 1 or 2.
  • Customize any of the those watermark types millions of ways.
  • Save your custom watermarks for re-use or as templates for your next watermark.
  • iWatermark can rename batches of files, filter input files, and resize photo files.
  • iWatermark processes RAW images which most don’t.
  • iWatermark can add or remove IPTC/XMP info during batch processing of photos. It can remove GPS data for privacy.
  • IMPORTANT – with iWatermark you can use photos of different resolutions and orientations in a batch and still keep the watermark on each photo looking the same because of the Scaling tool. Scale means a watermark can take an exact percentage of the width no matter the resolution or orientation of each photo.
  • iWatermark has a sophisticated watermark editor that can create text, text arc, text banner, graphic, vector, line, QR, metadata and resize watermarks.
  • iWatermark can create a watermark that embeds IPTC/XMP data each time it’s used with or without a visible watermark. Great for news organizations.
  • iWatermark can help you use the right Image Rights Metadata for Google Search and better SEO.
  • iWatermark is extremely fast which is important as file sizes and processing of batches continues to grow.
  • iWatermark keeps a database of all watermarks that can be used with a click.
  • There are applications like Photoshop that can watermark an image but iWatermark has a watermark manager which can track hundreds of watermarks. The manager also allows locking/unlocking, embedding IPTC/XMP, searching, renaming, deleting, previewing, merging, exporting, batch processing and sharing of watermarks.

IMPORTANT: Never delete your original files. Watermarking copies your original file and adds a visible watermark to it. iWatermark does not alter the original it only creates a copy. So, always keep your original unwatermarked files for safe keeping. This is probably totally obvious to you but has to be said for beginners.

Quick Start Tutorial

Step 1 Load Photos

Even though iWatermark can do many things (watermark, resize, rename, etc.) it always starts with loading a photo or photos. In the screenshot below is the ‘Image Well’ this is the location at the bottom of the iWatermark window to drag and drop the photo, photos or folder of photos. Or tap in the center of the empty image well to get the standard dialog to select photos or a folder.

iWatermark Pro 2 Win Manual 10 iwatermark pro 2 manual
Image Well

After you deposit photos in the well, it looks like the screenshot below.

image well with thumbnails in iwatermark pro 2 for win
Image Well

To remove photos from the image well. Tap the gear to the right of the image well and in the list select, ‘Clear Images’.

IMPORTANT: select, ‘Watermark’ to watermark photos. Many people leave this item checked (below).

iWatermark Pro 2 Win Manual 11 iwatermark pro 2 manual

Step 2 Batch or Single Photo

2.1 Watermark Single Photo

    1. With a tap select one watermark from the watermark list on the left side of the window. Or control-click to select multiple watermarks.
    2. To process photos individually, tap the ‘Process Selection‘ button.
    3. Tap a photo to apply a watermark to it. It is automatically added to folders by date and time (or whatever you method you have set in ‘Output’). The 3 icons on the right side of the screenshot below get you to the folders, control the folder settings and the i icon opens the metadata window. Open the gear icon to clear the ‘Image Well’ or tap the x icon at top right of the image well.
    4. Tap, ‘Stop’, when done working on photos individually.

process selection in iwatermark pro for win

IMPORTANT: You can use as many visible watermarks as you want simultaneously on a photo or photos. For obvious reasons there can only be 1 metadata or stegomark watermark on a photo or photos at a time. 

2.2 Batch Watermark

The 'Process Select' and 'Process Batch' in iWatermark Pro for Win 10 & 11

    1. Select or drag photos to the image well.
    2. Select a watermark(s) on the list on the left side of the window that you want to use. 
    3. Tap the ‘Process Batch‘ button.
    4. At the top you will see, ‘Output Preview’ as all the photos are watermarked. The photos can then be found by default in the, ‘Pictures:iWatermark Pro 2 Folder’ inside that last folder will be a folder with named with date and time that contains the entire batch of watermarked photos.

In the next test you can add other actions.These are the steps to follow.

2.3 Add Other Actions

    1. Select or photo(s to the image well.
    2. Select watermark as above.
    3. Add an action like, ‘Resize’, by checking it on. In it’s panel. When it’s on you can select from preset size like these (below) or you can customize the size you want.iWatermark Pro 2 Win Manual 12 iwatermark pro 2 manual
    4. Tap the ‘Process Batch’ button.
    5. Photos will then be watermark. The ‘Output Preview’ window will indicate the processing is finished.

iWatermark Pro 2 Win Manual 13 iwatermark pro 2 manual

In the future you can turn on or off any of the other actions above, Filter, Resize, Rename, Thumbnails or IPTC. These actions can be done with or without watermarking for example you can resize photos without watermarking. A workflow can be developed where iWatermark in one pass can resize, rename, create thumbnails, add metadata and watermark a bunch of photos as you wish and then exported automatically to the ‘Pictures:iWatermark Pro 2 Folder’ inside that last folder will be a folder with named with date and time that contains the entire batch of processed photos.

2.4 Using Multiple Watermarks

Select 1 or more watermarks simultaneously on a photo or photos. Stegomark and/or Metadata watermarks can only be selected once. Text, QR Code, Text Arc, Text Banner, Graphic/Logo and Lines can each be used multiple times as watermarks.

Selecting Multiple Watermarks

    • Click once to select (highlight) one watermark. Selection means highlighted.
    • For a contiguous (continuous unbroken sequence) selection of watermarks, shift-click on the first and last photo in a group  of watermarks. This Selection means they all are highlighted.
    • For a discontinuous selection of watermarks, control-click (right button on a mouse) on each watermark.

Only a single instance of Metadata and/or Stegomark can be used at one time. To allow 2 or more Metadata watermarks at the same time would not make sense because there is only 1 place to insert that data. Same for Stegomark.

Demo Watermarks

Drop in some photos. Then on the left side of the window tap on each demo watermark to preview it. They are mostly self-explanatory.

iWatermark Pro 2 Win Manual 14 iwatermark pro 2 manual

Tap a watermark to select/highlight it. Then you can see that watermark appear on the photo depending the display size of the photo. Each watermark shows a different watermark type, tags and settings that you can use to learn about the app and then use in your own, much better, sets of watermarks.

For example, Demo 10 – Bates Numbering – this demonstrates the uses of tags to add identification numbering to legal, business and medical documents. This is a technique that can be applied using iWatermark Pro for Mac and Win.

Bates Numbering, also known as Bates Stamping, is an indexing method used for legal, business and medical documents. Bates Numbers are perceived as digital reference points used to uniquely identify and label each page in a set of documents.  

Bates Numbering is a technique heavily used by legal professionals. So, it’s mainly used in the field of law. Needless to say, legal documents can contain thousands of pages and indexing those pages with Bates Numbers makes retrieving information out of them much easier than it would be otherwise.

By applying sequential numbering to documents, it makes the task of organizing and identifying important documents a lot easier. For example, a paralegal can instantly search the document and locate the page containing information a lawyer needs to reference during a deposition. This is a huge time and money saver.

It works by assigning specific identifiers (numeric or combination of letters and numbers) such as case ID numbers, dates or company names to each PDF page. By default, Bates Numbers are located in the header or footer of the pages and can include a prefix and or a suffix or even to be combined with the existing header and footer text. 


Create A Watermark

Make sure to have chosen a photo or photos. Start by creating a watermark. There are 7 kinds of watermarks. For this first time we will create a Text watermark. It’s a good example for showing how all watermarks are created. The Text watermark is simple, easy and the most commonly used watermark.

The steps below are how each watermark starts. All watermark types are created in a similar fashion. 

  1. On the left site of the iWatermark window where it says ‘Add watermark(s)’, tap the ‘+’ button to see the dropdown menu you see below.

iWatermark Pro 2 Win Manual 15 iwatermark pro 2 manual

Or, another way is to go to the File menu, at top left of iWatermark, choose New Watermark from there. The same dropdown menu appears, select ‘Text…’ to create a new text watermark.

iWatermark Pro 2 Win Manual 16 iwatermark pro 2 manual

Select the ‘Text’ watermark to begin.

iWatermark Pro 2 Win Manual 17 iwatermark pro 2 manual

2. Your new text watermark will need a name (see above). Give it something descriptive because you soon will have many watermarks and the right name can help you find it, to use again in the future.

Once you save a name for the watermark the editor for a text watermark appears on the right side. Here you experiment with changing the settings for the text watermark. Go to Text watermark below to continue…

Visible Watermarks

Text Watermark

text watermark settings in iwatermark pro 2 for win

Text watermarks are easy to create. Text is sharp at any size and depends on the available fonts. iWatermark+ gives access to 292 beautiful fonts (many are Google fonts) in addition to the system fonts.

The screenshot (right) shows all the settings you see when creating a text watermark.

1) Name – Set the name you want for the watermark

2) Text – Set the content for the text watermark.

3) Insert – Insert into the content special characters like the © symbol for copyright or ™ for trademark, etc. Also you can insert Tags which are variables for IPTC or EXIF info in the photo. More info is here.

4) Font – Set the Font and the Font Size. Below you can see the font menu allows you to see all fonts in your system and select one for your watermark text.

iWatermark Pro 2 Win Manual 18 iwatermark pro 2 manual

5) Font size, effects, color, drop shadow, border details, etc.

iWatermark Pro 2 Win Manual 19 iwatermark pro 2 manual

6) Effect – Sets the effect like engrave, emboss, inverse, etc. To the right of 

iWatermark Pro 2 Win Manual 20 iwatermark pro 2 manual

Effects, set Color of the font, text drop shadow, and the direction of the light creating that shadow.

Normal – means no effect.

Inverse– Subtracts either the source image sample color from the background image sample color, or the reverse, depending on which sample has the greater brightness value. Source image sample values that are black produce no change; white inverts the background color values.

Inverse is a useful one that can be used because it keeps even fine text legible on images with variable tone backgrounds. The more white used with inverse the better. This is true for text and graphics. Black won’t do anything. It’s best to use white in either text or graphics for inverse mode.

iWatermark Pro 2 Win Manual 21 iwatermark pro 2 manual

Emboss and Engrave

iWatermark Pro 2 Win Manual 22 iwatermark pro 2 manual

Using the Effect Engraved on Text from the Text Watermark Settings

iWatermark Pro 2 Win Manual 23 iwatermark pro 2 manual

Using the Effect Engraved with Background on Text from the Text Watermark Settings

iWatermark Pro 2 Win Manual 24 iwatermark pro 2 manual

Using the Effect Embossed on Text from the Text Watermark Settings

Emboss Background and Engrave Background are semi-transparent showing the photo below. Emboss and Engrave use text color to fill embossing. Both are useful for subtle watermarking.

Currently, you only have control of one of two drop shadows in the emboss/engrave effect.

Outside shadow color is controlled. Inside shadow is fixed to black for Emboss and white for Engraved.

NOTE: Currently only works in Text watermark — not in Banner or Arc text or Graphic yet.

Black Shadow – exactly what you would think.

White Shadow – ditto

Outline – outlines the text.

7) Background Color – Set the Background color and Border details

8) Alignment – Set Alignment (left, center, right) of text and padding which puts more padding/space around the text.

9) Rotation – Change the rotation of the text.

10) Opacity – Set the Opacity/Transparency.

11) Scaling – This sets iWatermark apart because it give the options of relative and absolute scaling.

Relative (%) – the default setting, simplest to understand and use. Does exactly what most people want. In relative mode position is set by % from edges. No matter size of photo you will get the visually same results. Watermark size/position are affected by photo dimensions. On the photo page this setting allows you to set the relative position of the watermark (by %) irrespective of the size and orientation of each photo in a batch. Example: in a batch of 2 photos, one low and the other high resolution, a border watermark set to be approx 10 pixels wide on one low resolution photo might when measured be 20 pixels wide on the high resolution photo. In the past we only had a “Relative” mode, but some users requested an “Absolute” one.

Absolute (pixels) – set everything, position, fonts, borders, graphics and everything is in changed to work in pixels. “Absolute” metrics mode makes sizes/positions of everything independent of photo size. Watermark size and position will remain the same (in pixels) for all photos. Example: in a batch of 2 photos, one low and the other high resolution, a border watermark set to 10 pixels wide would on both photos be exactly 10 pixels wide.

Relative is for setting the watermark location by percentages. This becomes essential when you want a watermark to appear the same size and in the same place in a batch of photos that may all be different resolutions, sizes and orientations.

iWatermark Pro 2 Win Manual 25 iwatermark pro 2 manual

In the screenshot you can see the scaling dropdown menu is set to ‘No Scaling’ by default. That means you are working not in % but in pixels.

All the options for Scaling are seen in the dropdown menu above ‘No Scaling’, ‘Horizontal Scale To:’ and ‘Vertical Scale To:’

iWatermark Pro 2 Win Manual 26 iwatermark pro 2 manual

No Scaling – sets scaling to work in pixels.

Horizontal Scale To: – sets the scale to work horizontally in %.

Vertical Scale To: – sets the scale to work vertically in %.

12) Tile to cover image – repeats the text multiple times across the photo. This is important for those people who want to insure no part of the photo is taken.

iWatermark Pro 2 Win Manual 27 iwatermark pro 2 manual13) Pin – allows you to set the location of a watermark in such a way that it is the same on all photos, no matter their resolution or orientation (portrait or landscape). Pin allows setting the location in a general way to top,left or bottom,right, etc.

14) Location– Once you have set the general location with Pin you can fine tune that like this. Below you see ‘Offset X’ and ‘Offset Y’. Depending on which Pin you chose you can change X and Y, X or Y. X is the horizontal direction and Y is the vertical direction.

iWatermark Pro 2 Win Manual 28 iwatermark pro 2 manual

If you are are watermarking one photo there are easier ways to set the location but the reason it’s like this is too allow watermarks to appear in the same spot whether you’re watermarking one or a thousand photos of different sizes and orientations.

The Text Watermark has the most settings so we started with it. For each of the following watermark type we only add the description of settings not included in the Text Watermark.

Tags in Text Watermarks

Tags in iWatermark Pro 2 for Windows

Tags are extremely useful. Use ‘Insert Tag(s)’ in all text watermark settings (seen above) to put Metadata (like camera model, creation date, sequential numbering, file name, location, etc.) from that photo or video into a visible watermark on that photo or video. Use these to create your own customized watermark to display a variety of info on your photos that will be different depending on the metadata in that photo.

This can be used in a variety of ways. Here is an example.

iWatermark Pro 2 Win Manual 29 iwatermark pro 2 manualExample 1: Let’s say you want to put a unique number, like a serial number on each photo in a batch of 119. In the above screenshot you can see how the and tags are added to a text watermark and placed on the photo. Now each photo in the batch will have a unique Counter and Total. It can be seen in action at the bottom left of the photo above in the zoomed in photo below. This shows the photos are each numbered correctly in this case, Number 021 of 119. Very handy!

Example 2: Add the Latitude and Longitude to 1 or 10,000 photos using tags. Seen at the right while making the watermark with preview.

Example 3: Let say you are a reviewer of cameras for a magazine or website and want to test the photos from a particular camera. To do this you need to show the different specs for hundreds of photos taken in a variety of different ways. A daunting organizational task. iWatermark Tags make this task much easier because now you can put the specs of a camera’s settings, at any particular moment a photo is taken, on each photo.

iWatermark Pro 2 Win Manual 30 iwatermark pro 2 manual
This image shows labels with tags displaying the tag name and GPS (latitude and longitude) of a particular photo.

Text On Arc Watermark

An Arc Text Watermark produces a watermark of text on a curved path. 

iWatermark Pro 2 Win Manual 31 iwatermark pro 2 manual

On the right are all the Text Arc settings. It has the settings seen in the Text watermark and more. Those additional settings are described below.

Autosize Radius – automatically sets the radius needed to fit the text so ends meet. This overrides Radius below.

Radius – text on the outside of the arc

Text A or ∀ – render the text right side up or upside down.

Angle – rotates the text around the arc.

Angle – change the angle of the text on the arc. Or rotate the angle with the circle with dot icon.

Other settings not mentioned here will be found in the Text Watermark settings above.

Text On Banner Watermark

A banner watermark is text with an adjustable background. See banner at the bottom of this photo below.

iWatermark Pro 2 Win Manual 32 iwatermark pro 2 manual

Above is the settings dialog for the Banner watermark. As you can see it puts an adjustable banner on any side of a photo. The settings are very familiar, most of them are the same as the Text watermark. The only difference is a radio button that allows choosing vertical or horizontal.

Logo/Graphic Watermark

Graphic Watermarks are good for logos, art, and signatures. Use your logo or any graphic but they need to be a special graphic format called .png with a transparent background. The sample signatures, symbols and other graphics we include have transparent backgrounds and are .png files. That means that even though the graphic is square only the signature itself shows and that which is not the signature is transparent allowing the background photo to show through. The file format to do this is called .png with transparency and it allows the background of the watermark to be transparent (a .jpg does not allow this transparency, .png must be used).

iWatermark Pro 2 Win Manual 33 iwatermark pro 2 manual
Bitmap Graphic watermark settings dialog.

This is for logos and other graphic art.

1. In the watermark editor click ‘Add New Graphic’. You can choose any graphic file like your logo to act as a watermark. Graphics are best when they are .png files with transparency so the background does not show. See the FAQ for more details.

2. Click on any of the Tools to change the rotationtransparency, etc. Give it a name and hit save.

3. Your new watermark is added to the dropdown menu (seen above). Choose it or any other to watermark a photo. Use the – button to delete the displayed watermark

Signatures – adding your signature as a watermark using a Bitmap Watermark.

You need a .png file of your signature. This can be created in a variety of ways.
The easiest way is to ask for it from your graphic designer.
Do it yourself. First, sign your name with a black pen or marker on white paper. 
Next, use your phone to take a snapshot of your signature on the paper or use a desktop scanner.
Use photoshop or use the Preview app that comes on all Macs.

Lines Watermark

iWatermark Pro 2 Win Manual 34 iwatermark pro 2 manualLines watermarks are most often seen in use by stock photo companies. The Lines watermark draws that radiate out from the center of a photo. The main idea is that this is a strong method to prevent people from copying the photos as it would create a lot of work to make those lines disappear as they cover most areas of the photo.

The settings for Line watermark are shown in the example screenshot. The settings are pretty obvious. It is worth testing them all out to see exactly what they do. The setting that is not obvious is opacity which is found after you click on line color. The dialog is seen at the bottom right of the screenshot above. At the bottom of that dialog is the drag bar for opacity.

QR- Code Watermark

A QR Code (it stands for “Quick Response”) is a cell phone readable bar code that can store website URL’s, plain text, phone numbers, email addresses and pretty much any other alphanumeric data up to 4296 characters. A QR can make a great watermark.

The QR example image below holds our website URL, https://plumamazing.com. Both the camera apps on iOS (in iOS 11) and the pure Android Camera app can scan and act on the info in a QR code. Chrome also can read QR codes on both Android and iOS. There are also many other QR scanner apps available in the app stores. Scan the QR code below and you get the choice to go to our site automatically. You can make one for your site or to any page with any info you want to display.

iWatermark Pro 2 Win Manual 35 iwatermark pro 2 manual

Usage examples. QR’s can be handy as a watermark on photos and other graphics that can hold the name, email, URL to take people to your site or other info depending on your creativity.

1. Someone might have QR watermarks for a bunch of photos and each QR could lead to its own web page with information on location, conditions, pricing, etc.

2. Watermark your photos with a QR that contains your URL, email, copyright, and other info. Good for maintaining your connection with a photo for Facebook, Twitter, and other social media. When you upload a photo to social media sites they often remove metadata. Social sites do not remove visible watermarks like text, signature, graphics or QRs.

3. Make an instructional video to Vimeo, YouTube, etc. or your site. Put the direct link to your video into a QR. Get some of the paper for printing out stickers and print out a bunch of these QR codes. Now slap this QR code onto a manual. When the user needs more visual help they can scan the QR to go directly to the video.

Invisible Watermarks

The two watermarks below when applied are invisible in that they aren’t seen on the surface of a photo like visible watermarks are. The data is hidden in that file.

Metadata Watermark

metadata editor in iwatermark pro 2 for windows
Click to view

Metadata is text and numbers in the file format of the photo. The Metadata Watermark can add to add to, modify and delete metadata in a photo. Metadata is a number of different types of information about the photo. Metadata watermarks are very simple to create. The screenshot (to the right) shows the Metadata Watermark screen. 


Stegomark Watermark

Stegomark is the iWatermark steganographic watermark. This is a watermark that hides information in the color info of the photo itself. A color photo is actually lots of numbers. Numbers that describe the color and location of pixels. In this vast quantity of numbers, there is space to hide a few more numbers. That is what Stegomark does is encrypt the info you want into the photo data and unencrypt that same data. Stegomark was created and is unique to iWatermark.

Someone could crop out your visible watermarks from your photo but a Stegomark is much more likely to remain embedded in a photo because it is invisible and more resilient to jpg compression, cropping and other changes than a visible watermark.

IMPORTANT: Only 1 Stegomark can be used at a time. Whereas you can select multiple visible (text, graphic, qr, etc.) watermarks simultaneously to watermark a photo. There is no limit on the number of photos that be processed with a StegoMark at once.

IMPORTANT: 25 characters or less (recommended) in a Stegomark allows it to be most resilient when resaving/recompressing a watermarked .JPG photo. Up to 80 can be used but it will impact the resilience of the message. Remember you can use a URL shortener to make a URL smaller for embedding.

IMPORTANT: Stegomark only works on .jpg files. It is best used on photos that are high resolution images. Photos with different patterns, colors, textures can hold more info from a Stegomark. 

Example 1: A small low resolution image with a large expanse of clear blue sky may show artifacts. The numbers making up this image are similar and very orderly. There is less entropy and therefore less room available for Stegomark info.

Example 2: A high-resolution image of a forest, trees, grass, or sky has more entropy (in terms of all the numbers making it up) and therefore more room for Stegomark information.

Stegomark is the first-ever implementation of a steganographic watermark for photography and is only available in iWatermark. Steganography refers to any process of embedding some data invisibly into the actual photo image data.

Stegomark because it combines Steganography, often called Stego for short and Mark from the word Watermark. Stegomarks uses a special algorithm designed at Plum Amazing. This specialized encoding makes that data almost impossible to decipher without iWatermark. If there is no password then any copy of iWatermark can reveal hidden text hidden in a photo by iWatermark. If there is a password then only a person with the password and iWatermark can reveal the hidden text.

One way to use Stegomark is to embed your email address or business URL into a photo. This along with a Metadata and a visible text or logo watermark gives different layers of protection to your credentials in a photo. Each separate watermark layer will resist in different ways things that can be done to a photo like cropping, resaving, renaming, etc. to maintain your ownership information.

Create A Stegomark

To begin open the ‘Watermark Manager’ page and select the blue ‘+’ icon and you will see this dropdown menu:

iWatermark Pro 2 Win Manual 36 iwatermark pro 2 manual

Select the last item Stegomark…

For ‘Name’ put a good descriptive name for this Stegomark.

When you drop in the input a batch of photos and have a stegomark selected, hit process and a dialog pops up asking for the password or no password.

In ‘Text’ put the text you want to embed in the image data.

Using no password anyone with iWatermark can read your message but highly unlikely for anyone to read it without using iWatermark. For even more privacy, enter a password, then only someone with the password and iWatermark Pro can read that text message buried in the photos image data.

Once this is done, export the Stegomark’ed photo. Check out the next section to see how to see your hidden info.

Click to view

View/Check a Stegomark

The first and easiest way to read a Stegomark is to go to the ‘Windows’ menu, select the item called ‘Stegomark Viewer’

Drag your photo in, or use the select button. If there is no password it will immediately reveal the content. If there is a password then type in the password and tap ‘Apply’. Here the revealed text says ‘info@plumamazing.com’.

stegomark viewer in iwatermark pro 2 win

The 2nd way to read a Stegomark, open the exported Stegomark watermarked photo by dropping it into the input well of iWatermark Pro or using the open from the file menu.

Then on the left edge of the input well tap the the i with a circle around it icon. That will open the info window. Click on the Stegomark icon in this info window as seen in the screenshot below. Enter the password if you have one.

Watermark List

The Watermark List is unique to iWatermark. Here is where all custom and demo watermarks are kept. Watermarks can be:

  • Created – right click or tap the ‘+’ sign icon at bottom left of screenshot below.
  • Deleted – right click and choose ‘delete’ or tap the ‘-‘ sign icon at bottom left.
  • Selected – to watermark an image. One or more can be selected.
  • Saved – saved here for reuse anytime.
  • Modified – Single click on a watermark or right click and select ‘edit’.
  • Renamed – right click and choose ‘rename’ or change the name at the top of settings on the right side.
  • Exported – to backup and share a watermark via email or social media.
  • Locked or Unlocked – when locked they are protected and can’t be edited or deleted. Tap on the lock icon to lock/unlock.

To create a new watermark. Click the ‘+’ icon at the bottom of the Watermark List and see the numerous watermark types you can create (screenshot below).

New Watermark Menu

Here select the type of watermark you want to create.

b. Watermark Editor

To create a new watermark click new watermark in the File menu or click the + button and you will see this.

iWatermark Pro 2 Win Manual 38 iwatermark pro 2 manual

Clicking any of the above items will open the Watermark Editor to create that watermark type. There is a different editor for each watermark type. Here is what the Text Watermark editor looks like:

iwatermark pro 2 for windows user interfaceTap to enlarge

2. Filter

Set the filter to allow certain types of files to be processed.

iWatermark Pro 2 Win Manual 39 iwatermark pro 2 manualFilter

filter panel in iwatermark pro 2 for windows.png

Filtering can be turned on here on or on the main page. If you drop a folder in the input filled with all kind of different format photos but you only want to watermark the .jpg files then filtering can help you. Filter the input files on attributes, keywords and/or metadata.

3. Resize

Change the size and sampling of the processed photos.

iWatermark Pro 2 Win Manual 40 iwatermark pro 2 manualResize

resize panel in iwatermark pro 2 for windows.png


Turn on resizing on this or the main page to resize or watermark and resize. Resizing takes the original and produces a copy that is a particular size. It reads resize within width and within height and that means it will resize the photo within those dimensions. You can also use the handy presets which are commonly used sizes to resize to.


Is used to change the sampled resolution. What does this mean? Here is a good explanation.

4. Rename

Rename all the processed photos automatically.

iWatermark Pro 2 Win Manual 41 iwatermark pro 2 manualRename

rename panel in iwatermark pro 2 for win

Turn on rename here or on the main page. Renaming makes copies of the input files and renames them whatever you decided based on your selection above. Select the tag you want to add to the name of the file(s) or type in your own prefix/suffix. The tags are variables that stand for that info in the photo. Model will put in the model of the camera in the name of the new file. Counter will increment by 1 for each photo processed.

TIP: On Windows click Start menu, and then click Control Panel then click Date or Time. Set the Time and Date format on the Mac. Go to Language & Regions in System Preferences then hit the Advanced button.

TIP: Drag in/out the various tags (date, time, camera, model, etc.) and look at the preview to get a taste of what a file name will look like.

5. Output

iWatermark Pro 2 Win Manual 42 iwatermark pro 2 manual Output

output panel in iwatermark pro 2 for windows.png

On the left side of this pane are the File Settings

Here you can change the file format, extension, quality and JPEG progressive. Many export settings are available here too.

Image format: change the output format from jpeg, TIFF, Photoshop PSD, PNG, BMP and JPEG 2000.

File extension:don’t change this unless you know what you are doing and have a specific reason. Some people asked for this ability but it means that double clicking the icon will not open up apps that rely on that extension.

Quality: changing the quality slider means that you change the JPEG compression. It can go from 100 which means that the quality is exactly the same or lossless. Unfortunately, setting to 100 increases the file size, this is true of all applications. We recommend a setting of 65 which is by default. 65 gives great quality and slightly smaller sizes than the original file. More detail about the quality are described in this online article:

Another excellent article on this:

Both should help you understand why we recommend 65 but leave it to you to change as you wish.

Lowercase Extension: makes the extension lowercase. Turn it off to have it have it retain case.

Use JPEG Progressive (recommended): This is recommended. Progressive JPEGs (p-JPEGs) are typically slightly smaller than baseline JPEGs, but their main advantage is that they appear in stages, giving the effect of the image fading in, similar to interlaced GIFs, as opposed to painting from the top down

On the right side of this pane are the Folder SettingsiWatermark Pro 2 Win Manual 43 iwatermark pro 2 manual

The folders can be set to be created and used automatically (default) or manually where you can set the folder location yourself. Screen on right.

Output Structure Menu: Date and Time (Sub Folders) is the default but can change to any of the other options in this menu. This is how your watermarked photos are saved, menu below.Output Folder Structure Settings

7. Thumbnails

Create thumbnails of the processed photos.

iWatermark Pro 2 Win Manual 44 iwatermark pro 2 manualThumbnails

thumbnails panel for iwatermark pro 2 for windows.

Turn on thumbnails here or on the main page to get a thumbnail of certain dimensions for each processed file. The thumbnails are processed directly into the output folder with any other photos but with the extension thumb to differentiate them from the regular photos.

Select the “Use separate folder for thumbnails” if you want to have all the new thumbnails in a new folder in the output folder.


All the above EXIF, IPTC, and XMP are types of Metadata. iWatermark can do 3 things with metadata.

1. It can add and remove metadata from a photo or photos.

2. It can add and remove metadata from a watermark.

3. Metadata can be displayed in a visible watermark.

First we will talk about point 1.

1. Adding and removing metadata from a photo or photos.

iWatermark Pro can preserve, remove and embed meta tag info. Also this metatag info can be used to watermark photos. More details on EXIF, IPTC, and XMP here.

iWatermark Pro 2 Win Manual 45 iwatermark pro 2 manualEXIF/IPTC/XMP

metadata panel for iwatermark pro 2 for windows.

Preserve existing metadata – Turned on by default. This duplicates all the metatag info in the original file into the copied file.

Add enabled IPTC/XMP metadata – When this is selected all the checked metatags (user customized) in the dialog above are added to the copy of the original file.

The drop-down menu which says Basic, Professional and Corporate allows you to select the number of metatags you want to edit and use. All the items you check off will overwrite existing info in the file.

TIP: Under TIFF ‘iWatermark Pro’ is added under Software (seen below).

If you need to search using metadata for all watermarked images then this will work.

2. Adding and removing metadata from a watermark.

The usefulness of adding metadata to a watermark is that then each time you watermark a photo it adds a particular set of metadata at the same time.

iWatermark is the only program we know of that can do this. Why is this useful? As a photographer, you can have a watermark that puts a visible watermark with your logo on top of the photo and simultaneously adds metadata you selected like your copyright, your company name, URL, email and/or any other text data you want.

How to embed metadata into a watermark. 

  1. First, select a watermark. 
  2. Next, go to the EXIF/IPTC/XMP panel and enter the data you want to embed into the watermark. 
  3. Then to the Watermark Manager and select the settings dropdown menu and choose the Embed item.

This info will show up in the column for IPTC/XMP in the Watermark Manager and look like this.

iWatermark Pro 2 Win Manual 46 iwatermark pro 2 manual

3. Metadata can be displayed in a visible watermark. This is called a Tag.

To do this create a new text watermark select EXIF, IPTC and XMP metadata variables like Camera Model as text for a watermark which will when processed display that info as a visible watermark on the photo(s). Select the tag info from this menu when making a watermark:

iWatermark Pro 2 Win Manual 47 iwatermark pro 2 manual

Demo on a photo of using tag metadata in a Text Watermark on a photo. It also shows metadata like ‘Creator’ and ‘Copyright Info’ added from the Metadata panel.
iWatermark Pro 2 Win Manual 48 iwatermark pro 2 manual

9. Advanced

Advanced because they are settings that don’t normally need to be changed. Also it’s good to read about them first before changing them.

iWatermark Pro 2 Win Manual 49 iwatermark pro 2 manualAdvanced

iWatermark Pro 2 Win Manual 50 iwatermark pro 2 manual

Preferences on the left side

Use Pixels vs % in Editor – when enabled (default) uses pixels for measures (relative). When setting is off uses percentage (absolute) for measures.

Fast parallel processing – takes advantage of more cores if the hardware has them and so is faster.

Enable save backup files – this pairs with the button below that shows the location where original files are stored so if the user overwrites their original their is always the backup.

Display color profile in editor – if on, then the color profile is used in the watermark editors settings. Turning this on requires more power cpu/gpu. The output is the same.

For images without embedded color profiles use:
RGB profile:
CMYK profile:
Gray profile:

Add select ICC profile if not defined in input

Remove input and adding selected ICC  profile

Buttons on the right side

Show Library Files – opens the folder where Watermarks folder, ColorProfiles, Images, iWatermark Pro 2 Backups and Metadata that you’ve saved, resides. Also you can get to it here:
C:\Users\info\AppData\Roaming\iWatermark Pro 2

We recommend backing up your ‘Watermarks’ folder every once in a while. Or if you do full backup of drive then when you want to re-import your watermarks you can get them here.

Show Preference File – opens the folder to the location of the preference file and highlights it.

Show Backup Files – this button opens to the Backup folders. iWatermark Pro 2 makes copies of your original images, if the pref (on the right side) Enable Backups is checked on, to make sure there is a second copy. These backups can take up a lot of disk space over time, so, you may want to delete these backups if you haven’t accidently deleted any originals.

Reset All Defaults – resets the application to the original default settings. This is very useful to use if you encounter a problem.

For Images Without Embedded Profile – lets you choose various profiles that come on the Mac or Windows or that are loaded from Nikon, Canon or other software. More info about ICC color profiles is here.

Logging – this bottom area has a button on the right to ‘Open console log’. The checkboxes for filtering, scanning, IPTC, Writing files, Loading preferences… if on add that particular info to the log files. This is only needed when requested by our tech support. This info helps our programmers.


iWatermark Pro 2 Win Manual 51 iwatermark pro 2 manual

You’ve seen the different colors of the user interface displayed in screenshots (like the above) in the manual. The way that is done is in the ‘Advanced’ preferences seen in the last section. At the top of the screenshot below in the ‘Advanced’ preferences you can see the ‘Theme’ tab is selected.

Above you can ‘Choose theme’ and ‘Theme color’, to change the color of the theme then hit the ‘Apply’ button to confirm the choice. Change the ‘Font Size.

10. Register

iWatermark Pro 2 Win Manual 52 iwatermark pro 2 manualRegister

This tab is the place to enter your registration info if you bought iWatermark Pro from us and not the Apple App Store. Here is where you place the registration info we sent automatically when you purchased iWatermark Pro. Once you enter the info and hit the apply button you get a dialog that says you are now registered.

Using Windows Explorer

Applying Watermark from Windows Explorer. Since release 2.0.1 of windows version, you can apply a watermark from within the windows explorer. This feature is called shell extension. Right click on an image file (JPEG, PNG, TIFF, BMP, PSD) then select ‘Watermark with iWatermark Pro’ and in the hierarchical menu, one of the watermarks listed.

The image is now watermarked. Quick and simple.

Note: the file format will remain the same but you can control the image quality from the application’s main panel. Limitations of the shell extension:

1. One watermark at a time can be applied.

2. A thumbnail won’t be generated.

3. If the image file is locked by another application it won’t work.

4. A read-only file will be watermarked but then it will no longer be read-only but writable.

iWatermark Pro 2 Win Manual 56 iwatermark pro 2 manual

Q: Isn’t Digimarc the serious way for real photographers to do watermarks on photos?
A: Many thousands of serious professional photographers use iWatermark. The reason we developed iWatermark is because we had a need for watermarking our photos (several of us are photographers) and we wanted something that worked easily, cheaply and effectively. We investigated Digimarc and many other methods that embed a watermark in the image. We found Digimarc to cost hundreds of dollars a year (and they charge based on the number of images) and the Digimarc technique is not foolproof or really that practical. If you embed your data in some invisible fashion like Digimarc then people don’t see it. There is software that does visible watermarking, like iWatermark, and software that does hidden watermarking, like Digimarc. Say you have an iPhone and you lose it in a park, you are much more likely to get it back if it is engraved with your name (iWatermark) then if some info is hidden/encrypted on its flash drive (Digimarc).

Considering these facts we decided from the start that iWatermark should be straightforward, inexpensive, use visible as well as hidden watermarking. The most effective approach we decided was to make software that can batch process hundreds of images and put on a beautiful watermark (logo, signature, copyright, whatever). This notifies people right up front and out in the open of your ownership.

Can they remove it? Yes, but the same is true of Digimarc. When you save an image in jpg it is recompressed (jpg is a compressed format) the pixels all get shuffled around and rearranged thus losing the embedded Digimarc info. Unfortunately we are still early in the digital age and copyrighting intellectual property is not perfect. This is a problem for musicians, movie makers, photographers and software developers. I just did a google on the subject and found this interesting link by a photographer that states the case quite well.


Digimarc is like thinking you are protecting your land by burying a no trespassing sign under it. No one will see it and they will think its public land and that they can do what they want. Not very effective. The reality is that making it perfectly clear some property is yours is still the best means of protection and the first defense. That is why we created iWatermark. iWatermark was a conscious choice to use visible watermarking not hidden watermarking. We also wanted to provide a method that is easy to use, practical and inexpensive that everyone can use and understand. 

iWatermark Pro 2 has an invisible watermark called Stegomark which can be added at the same time but we still believe visible watermarks are the best photo protection technique at this time.

Finally, even when iWatermark becomes your first line of defense (for digital rights management) there is no reason why you can’t also use other methods like Digimarc.

Q: Why should I watermark the photos I put on Facebook, Twitter, Instagram, Tumblr, etc.
A: Excellent question! Because all those services remove your metadata and there is nothing tying that photo to you. People can just drag your picture to their desktop and share to others till there is no connection to you and no info in the file that says you created or own it. A watermark makes sure that everyone is clear on the fact that the photo is your IP (intellectual property). You never know when a photo you took will go viral.

Q: I got a watermark from a friend. When I imported it, it did not look exactly like theirs?
A: We worked hard to make sure that you can export and share watermarks to other computers and have it look the same but a difference can be caused by these factors:

1. Different operating systems do things slightly differently with graphics, color, display, etc.

2. Different fonts. If you don’t have the same exact font as they do then there will be a difference in the look. It might even be the same font but a different version.

Font Solution:

1. get your friend to send you the exact font.
2. find free or buy the same font online.
3. make sure you downloaded the font and plugin installer, installed the fonts from that because that is many of the extra fonts used on iOS and Android.

Q: When I rotate my watermark text 90 or 270 degrees, it becomes very, very small. It is like the width/height-percentages doesn’t follow the rotation angle.
A: This is a result of the method you choose for scaling. When you create a watermark in the watermark editor by default it is set to Horizontal. If you choose Horizontal or Vertical it will do that jumping around, getting smaller and larger, but if you choose unscaled then it will behave normally. It is important to understand the tradeoffs of using Unscaled, Horizontal and Vertical scaling. Those tradeoffs and why iWatermark works the way it does is explained here.

Q: When I use a tag within a watermark I am not seeing any watermark show up?
A: You need to have photos that have that tag embedded in them or nothing will show on the photo. Another way that would work is to pushing tag into that you entered into the EXIF/IPTC/XMP area of iWatermark.

Q: How do I use my Photo Browser with iWatermark?
A:Lightroom, Xee, iMedia, ACDSee, Photos, QPict and other image browsers can all be used easily with iWatermark Pro.

Drag or select a photo or folder into iWatermark Pro and then watermark as usual.

Q: iWatermark Pro 2 is so much faster than iWatermark Pro but I have to process thousands of photos. Do you have any tips for optimizing the speed?
A: Upgrade to Win 11. If you are using Win 10 32 bit upgrade to 64 bit or to Win 11. Close the info window if open. Close the preview pane if open. Input on one drive and output on another. More and faster processors, more memory and faster drives like SSD drives or RAID drives all can help. Also know that we are always working on improving the speed.

Color Profiles

Q: Why are items in the watermarked photo colored differently than items in the original photo?
A: This can be caused by an issue with Color Profiles. Color Profiles are quite complicated. On the Mac, Color Profiles are usually an issue unless you are trying to get what you see on a monitor to be the same as what you print. On Windows, the issue can arise more often.


    1. Close Lightroom.
    2. Go to Start menu > Control Panel > Color Management.
    3. Click the Devices tab if it’s not already selected.
    4. From the Device pop-up, select your monitor. If you have more than 1 monitor connected, pressing the Identify monitors button will display a large number on screen for identification.
    5. Check the ‘Use my settings for this device’ checkbox.
    6. Make a note of the currently selected profile, which is marked as (default). If there isn’t an existing profile, you can skip this step.
    7. Click the Add button.
    8. In the Associate Color Profile dialog, select sRGB IE61966-2.1 (sRGB Color Space Profile.icm) and press OK.
    9. Back in the Color Management dialog, select the sRGB profile and click Set as Default Profile, and then close the dialog.

Here is more info on Color Profiles.

Q: If a CMYK image is in the process batch, will it change the color mode to RGB?
A: Yes it will, iWatermark currently only deals with RGB, so it will open a CMYK image, but converts it in the process.

Q: Which RAW file formats does iWatermark Pro read?
AWindows users can get Microsoft’s Camera Codec Pack and install it. 


Q: Should I use RAW to shoot?
A: That is an excellent question. It depends on you and what you are doing. This article does a good job of covering it.

Q: Can I use some of the metadata to watermark the file?
A: Yes, we recommend trying it out because it can be very useful. Go to the ‘Add a text watermark’ drop down menu choose ‘Metadata’ select from one of the EXIF, IPTC or other choices and it will drop in a text variable that will insert the right data when processing.

Q: What is XMP? What is IPTC? What is EXIF?
A: See the terminology section.

Q: Can I use iWatermark on 2 computers?
A: Yes, if you are the only user. If you and someone else will be using iWatermark on both machines for that the license requires buying another copy.

Q: How big a file can iWatermark Pro watermark?
A: It depends on the amount of RAM memory

Q: I use Lightroom. Why should I use iWatermark?
A: iWatermark provides watermarking tools not available in Lightroom. For example, a text watermark in Lightroom is one fixed size in pixels so that watermark will vary depending on the resolution of the photos being watermarked. Whereas iWatermark has text watermarks that optionally scale proportionally depending on resolution or portrait/lanscape. Lightroom uses pixels to determine watermark location whereas iWatermark position the watermark proportionally based again on esolution or portrait/lanscape. That means if you watermark a batch of photos of different resolutions and/or landscape or portrait orientations that iWatermark can have a watermark that maintains the same look/identitiy on all these kinds of photos.

iWatermark also has options not to scale. These are 2 big differences.

Q: There are temp files created in a Temp file folder. Should I delete them?
A: Yes, you can go ahead and delete Temp files. The system usually takes care of that for you.

Digital Watermarking – the process of embedding information onto or into a media file which may be used to verify its authenticity or the identity of its owners.

Watermark – a visible and/or invisible digital watermark that identifies the owner of a particular piece of digital media.

Visible digital watermark-info visible on a photo. Typically, the information is text or a logo, which identifies the owner of the photo. That info is merged into the image info but still visible.

Invisible digital watermark– info embedded within the image data of the photo but is designed to be imperceptible to human vision so it is hidden info. Steganography uses the same technique but for a different purpose.

Metadata– is the descriptive information embedded inside any type of file. All the items below EXIF, XMP, and IPTC are metadata that is added to a photo. Metadata does not change the actual image data but piggybacks on the file. Facebook, Flickr and other online social platforms remove all this metadata (EXIF, XMP and IPTC).

EXIF– Exif – Exchangeable image file format (Exif) A type of metadata that almost all digital cameras store within photos. EXIF stores fixed info like date & time taken, camera settings, thumbnail, descriptions, GPS, and copyright. This info is not meant to be changed but it can optionally be removed from photos. The specification uses the existing JPEG, TIFF Rev. 6.0, and RIFF WAV file formats, with the addition of specific metadata tags. It is not supported in JPEG 2000, PNG, or GIF.


IPTC– is a file structure and set of metadata attributes that can be applied to text, images, and other media types. It was developed by the International Press Telecommunications Council (IPTC) to expedite the international exchange of news among newspapers and news agencies.


XMP– Extensible Metadata Platform (XMP) is a specific type of extensible markup language used to store metadata in digital photos. XMP has subsumed IPTC. XMP was introduced by Adobe in 2001. Adobe, IPTC, and IDEAlliance collaborated to introduce in 2004 the IPTC Core Schema for XMP, which transfers metadata values from IPTC headers to the more modern and flexible XMP.


Tag– is one piece of metadata. Each item within EXIF, IPTC, and XMP is a tag.
