From developers to developers: a cross-platform tool for losslessly image compression.

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

OptiPNG is a command-line PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.
