pngquant 2.12.6

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:

  1. High-quality palette generation using a combination of vector quantization algorithms.

  2. Unique adaptive dithering algorithm that adds less noise to images than the standard Floyd-Steinberg.

  3. Easy to integrate with shell scripts, GUIs and server-side software.

  4. Fast mode for real-time processing/large numbers of images.

Installation

Install pngquant 2.12.6 as follows:

guix install pngquant@2.12.6

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
