pngquant — lossy PNG compressor
by Spone
pngquant is a command-line utility and a library for converting 24/32-bit PNG images to paletted (8-bit) PNGs.
The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency. Generated images are compatible with all modern web browsers, and have better fallback in IE6 than 24-bit PNGs.
