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.

AVIF
AVIF emerged from the Alliance for Open Media's work around AV1 and uses the HEIF family as its structural container, which connects it to both modern web delivery and newer image-container design.
