The Compressonator is a handy, easy to use application specially designed to help you compress textures and create mip-map levels. GPU Tools, Texture compression made easy.

A tool for compressing textures and creating mip-map levels. The results of compression can be visualized by comparing the original and the compressed textures.

Textures (and directories containing textures) can be explicitly compared to other textures or directories.
Also, you can batch compress any number of textures.

There are several types of compression available: DirectX and Grayscale texture compression in addition to palletized texture decoding. The options for these methods can be set from dialogs.

When comparing textures, the intensity of difference can be increased by as much as 3200%.
