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.
MIFF at a glance
MIFF
MIFF reflects the older tradition of image-processing toolkits defining their own native technical formats for fidelity and internal workflow convenience.
