AVIF to HEIC can't be done in your browser
AVIF to HEIC can't be done in your browser
Creating a HEIC file needs an HEVC encoder, which no web browser includes and which can't run privately on your device the way our other conversions do. Reading HEIC works in the browser — writing it doesn't — so an honest, no-upload HEIC converter isn't possible today.
WebP delivers the same roughly 50% size saving as HEIC, with far wider support — and it converts instantly, right in your browser.
Why convert AVIF to HEIC?
HEIC is Apple's photo format, built on the modern HEVC codec — but creating a HEIC file needs an HEVC encoder, and no web browser includes one. Reading HEIC works in-browser; writing it doesn't, so a private, no-upload HEIC converter simply isn't possible today. If you need a format with similar efficiency that works everywhere on the web, WebP is already in your browser and converts instantly here.
AVIF vs HEIC at a glance
AVIF is the newest mainstream image format — outstanding compression, but support outside browsers is still patchy. HEIC is Apple's default photo format — roughly half the size of JPG at the same quality, but barely supported outside Apple devices.

AVIF to HEIC — frequently asked questions
Why can't I convert AVIF to HEIC here?
Making a HEIC file requires an HEVC encoder, which no web browser provides. We only build converters that work entirely in your browser with no upload — an honest in-browser HEIC encoder isn't one of them.
What should I use instead of HEIC?
If you need broad compatibility, WebP is the closest alternative that works everywhere. AVIF itself is already more efficient than HEIC — if the recipient's device supports it, stay with AVIF.
