Why iPhone photos are HEIC (and how to open them anywhere)

If you have ever sent an iPhone photo to a Windows PC and been greeted by a broken thumbnail, you have met HEIC. Since iOS 11, iPhones save photos in HEIC (High Efficiency Image Container) instead of JPG by default.

Why Apple switched to HEIC

The reason is storage. HEIC stores the same photo at roughly half the file size of JPG with equal or better quality, because it uses the compression techniques of the HEVC video codec. Multiply that saving by the thousands of photos on a phone and the decision makes sense — for Apple.

The problem is that the rest of the world did not follow. Windows needs paid codecs to open HEIC natively, many Android apps ignore it, government forms and job portals reject it, and older software simply shows an error.

Three ways to deal with a HEIC file

1. Convert it to JPG — the universal fix. A JPG opens on any device made in the last 25 years. You can convert HEIC to JPG free in your browser — the file never leaves your device, which matters if the photo is a document or something personal.
2. Convert it to PNG if you plan to edit the image afterwards and want to avoid any additional quality loss. Here is the HEIC to PNG converter.
3. Change your iPhone settings so future photos are JPG: Settings → Camera → Formats → “Most Compatible”. Note your photos will take about twice the space.

Does converting lose quality?

Converting HEIC to PNG is lossless — every pixel is preserved. Converting to JPG at quality 80+ produces differences that are practically invisible on screen. What you should avoid is converting back and forth repeatedly, since each lossy re-encode stacks a little more degradation.

If the converted photo is for a form with a size limit, you can also compress it to an exact size like 100 KB after converting — both steps run locally in your browser.
