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