Nástroj pngquant pro optimalizaci obrázků PNG

pngquant converts 24/32-bit RGBA PNGs to 8-bit palette with alpha channel preserved. Such images are compatible with all modern browsers, and a special compatibility setting exists which helps transparency degrade well in Internet Explorer 6.

Quantized files are often 40-70% smaller than their 24/32-bit version.

This utility works on Linux, Mac OS X and Windows.

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.
