HEIC vs JPG: How to Open iPhone Photos on Windows

You copy photos from your iPhone to a Windows PC, double-click one, and get an error, or a prompt to buy an extension. Or a website's upload form simply refuses the file. The cause is almost always the same: the photo is a .HEIC file, not a JPG.

What HEIC is, and why your iPhone uses it

HEIC (High Efficiency Image Container) is the format iPhones have used for photos by default since iOS 11. It stores images using the same compression family as modern video, which lets it keep roughly the same visual quality as a JPG in a noticeably smaller file. Apple's own figure is about half the size. On a phone holding thousands of photos, that adds up to a lot of storage.

HEIC can also hold extras JPG can't, such as a Live Photo's companion data and depth information for portrait mode.

The catch is compatibility. JPG has worked everywhere for decades. HEIC support on Windows depends on optional extensions, and many web forms, older programs, printers and photo kiosks still only accept JPG or PNG.

The quick fix: convert HEIC to JPG

1. Open HEIC to JPG.
2. Drop a .heic or .heif photo into the box.
3. Click Convert to JPEG, check the preview, and Download your JPG.

The conversion happens inside your browser, so personal photos aren't uploaded to a server. Files are converted one at a time.

The JPG is saved at high quality, so for normal viewing, printing and sharing you won't see a difference. It will usually be somewhat larger than the HEIC, because JPG compression is less efficient. That's the price of compatibility.

JPG or PNG?

• JPG is the right choice for photos almost every time. It's smaller and accepted everywhere.
• PNG keeps the converted pixels without any further compression. It makes much bigger files, and since the HEIC was already compressed, it can't bring back detail that's gone. Choose HEIC to PNG only if an editing program or a form specifically asks for PNG.

Stop the problem at the source

If you regularly move photos to a PC, you can make your iPhone hand over JPGs:

• Shoot in JPG from now on: Settings → Camera → Formats → Most Compatible. New photos are saved as JPG. They take more space on the phone.
• Convert on transfer: Settings → Photos → Transfer to Mac or PC → Automatic. The phone converts photos to JPG when you copy them over a cable, and keeps HEIC on the phone.

Neither setting changes photos you already have, which is where converting comes in.

Common problems

"This file is not supported" when uploading. The site wants JPG or PNG. Convert first, then upload the JPG.

The converted photo is too big for an email or form. Run it through the Image Compressor and lower the quality slider until the size fits. For photos, 70 to 80 percent quality is usually indistinguishable on screen.

A file ends in .HEIF instead of .HEIC. Same family of format; the converter accepts both.

The photo looks rotated. Some apps ignore the orientation stored with a photo. Converting usually settles it, and Rotate Image fixes any that are still sideways.

Quick answers

Does converting lose quality? Very little at the high quality setting used, and nothing you'll notice when viewing or printing normally.

Is HEIC better than JPG? For storage, yes: similar quality in a smaller file. For sharing, JPG wins because everything can open it.

Are my photos uploaded? No. The conversion runs in your browser and the photos stay on your device.
