About RAS

Sun Raster

The native raster format of Sun workstations running SunOS, stored uncompressed or with run-length encoding. Convert from RAS to open images saved on old Sun systems.

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.
