Your iPhone has shot every photo as HEIC since you set it up. You would not have noticed, because the camera app plays it back fine. The trouble only shows up when the files leave the phone: a blank thumbnail on Windows, a rejected upload on a website, a question mark on an Android friend's phone.
If you keep running into that, the fix has two parts. Flip one setting so new photos are JPEG, and convert the HEIC photos you already have.
Why Your iPhone Uses HEIC
iOS defaults to HEIC because the format holds roughly half the space of JPEG at the same quality. Apple chose it to fit more photos in the same storage.
The trade-off is compatibility. HEIC needs a HEVC decoder, and that is not universal. Windows wants an extension, Android support varies, and plenty of services refuse the format. If you send photos to other people or upload them regularly, JPEG removes the friction.
Switch New Photos to JPEG
The setting lives under Camera > Formats.
- Open Settings.
- Tap Camera, then Formats.
- Under Camera Capture, select Most Compatible.
That is it. New photos are saved as JPEG from now on. The toggle says it plainly: Most Compatible saves in JPEG, High Efficiency saves in HEIC.
One caveat: photos will take up more space now. That is the price of universal compatibility, and on modern iPhones the difference is usually a few extra gigabytes over time.
What About the HEIC Photos You Already Have?
The setting only affects new photos. Every HEIC file already on your phone stays as HEIC. To make those usable everywhere, convert them.
Our HEIC to JPG converter runs in a browser and works through a whole library:
- Drop the photos. Select a few or a whole album's worth.
- Convert locally. The files are processed on your device, so nothing is uploaded.
- Download the JPGs. Grab them individually or as a ZIP.
You can also output PNG or WebP if those fit your needs better.
Still Getting HEIC in Some Cases?
A few camera modes record in HEVC even with Most Compatible selected. Burst shots, some HDR captures, and videos can still use the high-efficiency codec. If you spot a stray HEIC after switching, convert it with the same tool. The bulk of your photos will be JPEG.
Does This Change Photo Quality?
No. JPEG at the quality the camera produces is visually indistinguishable from HEIC for normal photos. You trade a little storage for a format that works everywhere. If you want to keep the smaller files, leave the setting on High Efficiency and convert only when you need to share.
FAQ
Where is the HEIC setting on iPhone? Go to Settings > Camera > Formats. Choose Most Compatible under Camera Capture to save JPEG instead of HEIC.
Does Most Compatible lower photo quality? No. Your photos stay at the same resolution and quality. They just use more storage because JPEG is a larger format.
Will switching delete my HEIC photos? No. The setting only changes how new photos are saved. Your existing HEIC files stay on the phone until you delete or convert them.
Can I convert my existing HEIC photos? Yes. Use our HEIC to JPG converter in the browser to convert the files already on your phone, then keep or delete the originals as you prefer.
Bottom Line
Open Settings > Camera > Formats and pick Most Compatible to stop new HEIC photos before they start. For the HEIC files you already have, convert them to JPG in the browser. That combination makes every photo you take and every photo you already own work on any device, any app, and any website.
