HTM

This is a very simple format where every pixel is saved as a cell in HTML table. You can view such files in every web browser, for eg. Firefox or Chrome.

DDS

DDS are files invented by Microsoft to be used in games, mostly as textures. Images can be compressed to save space but the compression methods defined by DDS are all very fast in terms of coding and decoding.
