PhotoShrinkr takes .jpg format files, examines them and figures out the best way to compress and maintain the highest visual quality. While you can compress files in PhotoShop and other apps the compression vs visual quality won’t be nearly as good as in PhotoShrinkr. This app was designed specifically to provide a quick and easy way to get best quality and highest compression. When you download it in it’s shareware/free form it has all features and can be tested on 1…100…1000… files at a time. Maybe we said this already but it’s really fast.

System Requirements


PhotoShrinkr requires Intel Mac OS X 10.6 – 10.9 or higher. Version changes info.

Quick Start Tutorials

This tutorial will guide you step by step in converting photos (any readable format) and optimizing photos in JPG image. 

JPG is the most popular image format for photos. It is a compression format.

IMPORTANT: PhotoShrinkr never deletes your original files. PhotoShrinkr copies your original file and optimizes it as JPG image. PhotoShrinkr never alters the original it always creates a copy.

By default a new PhotoShrinkr folder is created in your ‘Pictures’ folder. This is where all the compressed files are put. To open this folder easily just click the ‘Output’ button at bottom left and select a new folder. To change the folder to which files are saved, in the main window click on the ‘Preferences’ button and select a new folder.

4 areas of PhotoShrinkr window:

    1. File List – drop image files here and copy of the image is optimized to the output folder.
    2. Status area below the file list show current status and easy access to output folder and preferences.
    3. Next to the Status and summary of EXIF metadata from cameras.
    4. Above the metadata is preview of selected image with divider to see before and after optimizing.
