HEIF in sintesi

HEIF

HEIF was developed by MPEG and built on the ISO Base Media File Format lineage, which helps explain why it feels more like a modern media container for images than a simple legacy bitmap file.

PGM in sintesi

PGM

PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.
