Here's the short version: a Mac opens HEIC files with nothing to install. HEIC is Apple's own format, so macOS has read it natively since High Sierra (2017). If a HEIC won't open on your Mac, something specific is off — and the fix is usually one click.
The three built-in ways to open HEIC on a Mac
- Quick Look — select the file in Finder and press the spacebar. The photo previews instantly without opening any app.
- Preview — double-click the file (or right-click → Open With → Preview). You can crop, rotate, and annotate here too.
- Photos — HEIC imported from your iPhone shows up normally in your library.
When a HEIC still won't open on your Mac
A few things can trip it up:
- Very old macOS (before High Sierra 10.13) — no native HEIC support. Update macOS, or use the browser HEIC viewer.
- A corrupted or partial file— one that didn't finish transferring over AirDrop or email. Ask for it again, or try opening it in the browser viewer, which is more forgiving.
- An app that doesn't support HEIC— some third-party editors can't read it even though Preview can. Convert to JPG first (below).
Convert HEIC to JPG on your Mac
The reason most people search this isn't viewing — it's that they need to send the photo to someone on Windows or Android, upload it to a website, or attach it to a form that rejects HEIC. Two easy ways:
- Preview — open the HEIC, then File → Export and choose JPEG. Good for one file.
- Browser converter — drag your HEICs here and get JPGs back, up to 50 at once, without uploading anything. Faster for a batch, and it works the same on any Mac.
Prefer to keep photos as HEIC on your iPhone but have them arrive as JPG on your Mac? Turn on Settings → Photos → Transfer to Mac or PC → Automatic on the iPhone. More background in why your iPhone saves photos as HEIC.
On a different device?
The steps are different off the Mac. See opening HEIC on Windows, on Android, or the platform-agnostic how to open HEIC files guide.
