HEIF in het kort
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.
JXR in het kort
JXR
JPEG XR grew from Microsoft's HD Photo work and then moved through standards bodies, but it remained much more niche than formats such as JPEG, PNG, or later AVIF/WebP families.
