Why won't my website or app accept my iPhone photos?▼
iPhones save photos as HEIC by default since iOS 11. Most non-Apple platforms don't decode it, so uploads fail or get rejected. AVIF is a good target because it's open and cross-platform, and smaller than a JPEG re-export.
What to Know Before You Convert
Convert HEIC to AVIF when you've exported photos from an iPhone and need a format that opens everywhere else — most non-Apple software, many web forms, and most website upload tools don't accept .heic.
Not a size/transparency trade-off
Unlike the other conversions here, the problem isn't file size or transparency — it's that HEIC is Apple's format and most non-Apple platforms simply can't decode it.
Smaller than re-exporting to JPEG
AVIF is an open, cross-platform format that also compresses better than a JPEG re-export, so you get compatibility and a smaller file at the same time.
