About PGM
Portable Graymap
The grayscale member of the Netpbm family: uncompressed pixels after a short text header. Use it to feed grayscale images to computer vision and image-processing code that reads Netpbm.
About QOI
Quite OK Image Format
A lossless image format published by Dominic Szablewski in 2021, designed to encode and decode much faster than PNG at similar file sizes. Its whole specification fits on one page. Use it in games and tools that load many images and care more about decode speed than support in other apps.
