WEBP at a glance

WEBP

Google announced WebP in 2010 for faster image delivery on the web, and the format is now documented in RFC 9649.

PGM Raw at a glance

PGM Raw

The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.
