GUI for PNG and JPEG optimization.

Overview

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.

Thanks to the developer Kornel Lesiński and all 3rd party related developers for this great app! Cloud storage space and data transfers come at a cost, and whenever possible, size of a file should be reduced. Especially so when a file is shared with other people—thinking in the best interests' of others always pays off. ImageOptim is very helpful in this regard.

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.

★★★★★ A long-time favorite with many photographers for fast & easy optimization of PNG and JPEG images for web use. Highly recommended! Support development with a donation if you enjoy using it!

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!
