What is ImageOptim ?

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, pngquant, Pngcrush, 7zip, SVGO and Google Zopfli.

All free and open source
