High Efficiency Image Container — Apple's default photo format on iOS.
What is image/heic?
image/heic is the media type for HEIC images — the default format iPhone cameras produce since iOS 11. It halves file size compared to JPEG at similar quality but is not natively supported by non-Apple browsers.
Typical usage
iPhone/iPad photo uploads. Server-side transcoding to JPEG or WebP is usually required for cross-platform display.
Common gotchas
Browsers other than Safari cannot display HEIC. Detect the format on upload and transcode server-side.
