AMD Compressonator

Compressonator is a set of tools to allow artists and developers to more easily work with compressed assets and easily visualize the quality impact of various compression technologies.  

It consists of a GUI application, a command line application, and an SDK for easy integration into a developer toolchain.

Download the latest version - v4.5

This release adds the following features:

  • Improved compression ratios for most BCn textures using Brotli-G
  • A new Brotli-G zip packaging feature
  • ETC codec fixes
  • Various build improvements and bug fixes

Features

The SDK provides a variety of block based codecs, palletized and grayscale encoders, and useful tools for generating mip-maps, comparing the quality of compressed and uncompressed images and batch-compressing large databases of images are included.

Developers and texture artists can optimize the level of quality and performance that best suites the requirements for their game assets and pipeline. Textures are compressed according to specific data streaming requirements, balancing both power and memory of the targeted devices while maintaining quality that users expect.
