ImageOptim

Description

ImageOptim optimises images – so they take up less disk space and load faster – by finding best compression parameters and by detaching pointless comments and colour profiles. It handles PNG, GIF and JPEG animations.

ImageOptim seamlessly integrates with tons of the best optimisation tools: PNGOUT, Zopfli, Pngcrush, AdvPNG, extended OptiPNG, JpegOptim, jpegrescan, jpegtran, and Gifsicle.

It’s the best for publishing images on the web (easily compress pictures “Saved for Web” in Photoshop) and also helpful for making Mac and iPhone/iPad applications smaller.

How to put it to use
Simply drag-drop images or folders into the window! They’ll be optimised in-place.

You can also drop files on ImageOptim’s Dock icon, or use Services menu in Finder, or launch it from a shell script.
