HEIC conversion is about access to phone originals
Use this page when iPhone HEIC or HEIF photos need to work in upload forms, older editors or catalog systems. The key checks are orientation, detail retention and whether JPG compatibility or WebP delivery is the better final copy. Treat the downloaded file as the proof, not the preview alone. A phone original can decode correctly in one browser and still need review for color, rotation and memory before a larger batch.
