FileHint

image/heic

The MIME type for HEIC images — the ISO BMFF-based compressed format iPhones produce by default.

Typical extensions

Primary uses

  • iPhone camera output
  • Sharing inside the Apple ecosystem
  • High quality at a small file size

In a browser

Safari 17+ renders HEIC; Chrome and Firefox do not. Provide JPEG / WebP fallbacks on the web.

On a server

Serve HEIC only when `Accept` advertises `image/heic`; fall back to JPEG or WebP otherwise.

In email

Apple Mail renders HEIC; Outlook and Gmail treat it as an attachment. For distribution, use JPEG.
