HEIF at a glance
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.
PNM Raw at a glance
PNM Raw
PNM survived because engineers kept needing a no-drama raster family for scripts, fixtures, codecs, and image-processing experiments where the format should not be the hard part.
