GUI for PNG and JPEG optimization.
What is ImageOptim for Mac
ImageOptim is a front-end (GUI) for set of tools for optimisation of PNG and JPEG images.
Optimization makes files smaller (in terms of disk space) by finding optimal compression parameters and by removing unnecessary information, like file comments, EXIF tags, and color profiles.
Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

All the positive reviews here are deserved, but I want to add something that's essential, from my point of view, when dealing with PNG: you get even better results when using first ImageAlpha (by the same dev), it then automatically sends its result to ImageOptim and can achieve up to 90% gain!

This is a really good app for compressing images, especially PNGs. However, if you run it on a lot of images it kicks the computer fan on pretty hard. Not sure why.

It's so good that I actually want to pay for a free app. I use it everyday. Great support for many formats. Integrates with sites and automatic processes too. Thank you for this great tool. Very sporting of all contributors to open source to make it free.

Very nice, this update includes SVG optimisation!!! This adds to an already totally brilliant and essential tool for anyone. I use it to optimise figures before creating PDFs as I have more control in ImageOptim than any of the PDF optimising tools... It works just brilliantly, and integrates with services, so for example for screenshots I use a service that resizes the screenshot 50% and then runs automagically through ImageOptim with lossy enabled to get a PNG reduced by more than 80% in size on average from the original!
