HEIC from iPhone: Why It Won't Open and How to Convert It

What HEIC is in plain English

HEIC (High Efficiency Image Container) is a container for photos that the iPhone has used by default since iOS 11 (2017). Inside it, the shot is compressed with the modern video codec HEVC (also known as H.265) — the same one used for high-resolution video.

The main advantage is efficiency. At the same or even better quality, a HEIC photo takes up about half the space of the same frame as a JPG. On a phone holding hundreds or thousands of shots, that's serious storage savings. The format can also store extra data: Live Photos, depth maps for portrait mode, and an extended brightness range.

Why Apple switched to this format

Apple's decision makes sense once you look at the numbers. Modern iPhone cameras shoot at high resolution, and users hoard gigabytes of photos. If all of that lived in JPG, storage would fill up twice as fast. HEIC solves exactly that: the same memories, half the space.

Beyond savings, the format supports things JPEG simply can't:

• Transparency (an alpha channel) — JPG can't do this at all.
• Extended color and brightness (HDR) — shots look livelier on modern screens.
• Multiple images in one file — the basis of Live Photos and burst shots.
• Depth data — for the background-blur effect in portraits.

So HEIC isn't a whim — it's a technically more advanced format. There's only one problem, and it isn't technical.

Why the file won't open for everyone else

The root of all the trouble is licensing. The HEVC codec that HEIC depends on is patent-protected, and using it requires paying royalties. So many systems and apps deliberately don't enable HEIC support "out of the box," to avoid paying for a license.

In practice that looks like this:

• Windows. The default viewer often won't open HEIC until you install special codec extensions from the Microsoft Store.
• Android. Older versions and many apps don't understand the format; a photo you're sent may arrive "broken" or not display at all.
• Websites and services. Tons of upload forms, photo printers and online services accept only JPG and PNG — HEIC is simply rejected.
• Older editors. Programs released before the format spread don't open it.

How to convert HEIC to JPG

The simplest, most universal path is to turn HEIC into JPG. That format opens absolutely everywhere: on any computer, phone, browser or service, with no codecs at all. Through an online converter it takes mere seconds:

If you'll later edit the photo with layers or need to keep transparency, choose HEIC to PNG instead of JPG — PNG stores the image losslessly and supports an alpha channel.

How to make the iPhone shoot JPG directly

If you run into this regularly, you can set the camera so it never creates HEIC in the first place:

The price of compatibility is that photos again weigh twice as much, and you lose some HEIC advantages (HDR, efficiency). That's why many people prefer to keep "High Efficiency" on and convert shots only when they actually need to.

Keep HEIC or switch to JPG?

There's no one-size-fits-all answer — it depends on how you use your photos:

A sensible compromise: keep HEIC to save space, and when a photo needs to go somewhere, convert it to JPG in a second. All available conversions are gathered on the all formats page.
