Install pngquant - Lossy PNG Compression App on Linux

If you are looking for a simple image compression tool, check out pngquant, a command-line utility and a library for lossy compression of PNG images.

The app conversion reduces file sizes significantly (as much as 70% of original size) whilst preserving the full alpha transparency of the image. All generated images are compatible with all modern web browsers, as well as having a better fallback in IE6 than 24-bit PNGs.

Key Features

  • High-quality palette generation using a combination of vector quantizationalgorithms.
  • 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 processing large numbers of images.
