S3 Texture Compression (S3TC) (sometimes also called DXTn, DXTC, or BCn) is a group of related lossy texture compression algorithms originally developed by Iourcha et al. of S3 Graphics, Ltd. for use in their Savage 3D computer graphics accelerator. The method of compression is strikingly similar to the previously published Color Cell Compressio...

TL;DR: DXT compression is very similar to how JPEG compresses: fourier form and remove the low frequencies. Can result in artifacts.
