pngquant
Utility and library for lossy compressing PNG images
pngquant is a PNG compressor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format with alpha channel (often 60-80% smaller than 24/32-bit PNG files). Compressed images are fully standards-compliant and are supported by all web browsers and operating systems.
Features:
High-quality palette generation using a combination of vector quantization algorithms.
Unique adaptive dithering algorithm that adds less noise to images than the standard Floyd-Steinberg.
Easy to integrate with shell scripts, GUIs and server-side software.
Fast mode for real-time processing/large numbers of images.
