J2K in het kort
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
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.

It is a strong target in contemporary imaging ecosystems.
What changes when converting J2K to HEIF?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to HEIF removes vector scaling.
What should I review after converting J2K to HEIF?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
