Converts 24/32-bit RGBA PNGs to 8-bit palette with alpha channel preserved

Edit Package pngquant

pngquant is a command-line utility and a library for lossy compression of PNG images.

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.
