What is ImageOptim?

ImageOptim is a free, open-source image optimisation app for Mac, licensed under GPL v2 or later. It reduces image file sizes by removing metadata and applying compression, and by default it keeps image quality. It strips EXIF data, embedded thumbnails and comments, and an optional lossy mode gives smaller JPEG, SVG, GIF and PNG files. You can drag and drop files or use it from the Finder, command line and other tools. It needs macOS 11 or later.

Pros: what ImageOptim does well

  • Free and open source
  • Strips metadata to cut file size
  • Drag and drop or run from the command line

Cons: where it falls short

  • Only available for Mac
  • Not on the Mac App Store

Who ImageOptim is for

Mac users who prepare images for the web or want to save space.

Who can skip it

People on Windows or who only compress images occasionally.
