ImageOptim for Mac makes images load faster! ImageOptim is a front-end (GUI) for a set of tools for optimization of PNG and JPEG images. Removes bloated metadata. Saves disk space & bandwidth by compressing images without losing quality.

ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It's useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization).

Image Optim for macOS removes EXIF meta­data, such as GPS position and camera's serial number, so that you can publish images without exposing private information (but there's an option to keep the meta­data if you need it).

Features and Highlights

Faster web pages and apps
Reduces image file sizes — so they take up less disk space and down­load faster — by applying advanced compression that preserves quality.

Image files scrubbed clean
Removes invisible junk: private EXIF meta­data from digital cameras, embedded thumbnails, comments, and unnecessary color profiles.

Best tools with drag'n'drop
Seamlessly combines all the best image optimization tools: MozJPEG, Pngcrush, pngquant, 7zip and Google Zopfli. All Free and Open-Source.
