This is a front-end for open source tools: OptiPNG, pngcrush, advpng, jpegtran and jpegoptim.
Images are made smaller (in terms of disk size) by recompressing them using best combination of compression settings, bettter algorithms, and by removing optional, invisible information like comments.
ImageOptim takes advantage of multi-core and 64-bit CPUs.
What's new in this version:
- Option to Stop optimizations earlier (keeping progress made so far)
- Removal of "Where from" OS X metadata
- Lighter/faster default config on slow machines
- Updated pngcrush
- Autolayout used for the main window
