Need JPGs right now? Use the free HEIC to JPG converter — then read on for why this happens.
You transfer some photos to your computer, attach them to a form, or download them from iCloud — and instead of IMG_1234.JPG you get IMG_1234.HEIC. Nothing is broken. Here’s why your iPhone saves photos as HEIC, why you’re only noticing now, and how to get JPGs when you need them.
The short answer
Your iPhone’s camera is set to High Efficiency, which saves photos in the HEIC format. It’s been the default on iPhones since iOS 11 (2017). You can check under Settings → Camera → Formats.
Why does Apple use HEIC?
Apple switched to HEIC for three reasons:
- It saves storage. A HEIC photo is roughly half the size of a JPEG of the same quality. Across thousands of photos that’s a lot of space on your phone and in iCloud.
- It looks better per megabyte. HEIC uses compression from HEVC video, which preserves more detail with fewer artifacts than JPEG.
- It supports modern features. Portrait mode depth data, HDR information, Live Photo stills and bursts fit neatly into the HEIF container; JPEG can’t hold most of that.

Why am I only seeing HEIC files now?
Apple hides HEIC most of the time by converting to JPEG automatically when it thinks the other side can’t handle it. Whether you see HEIC depends on how the photo leaves your phone:
| How you move the photo | What you usually get |
|---|---|
| Email from the Photos app | JPEG |
| iMessage to an Android phone | JPEG |
| USB cable to a PC with “Automatic” transfer | JPEG |
| USB cable with “Keep Originals” | HEIC |
| AirDrop to a Mac | HEIC |
| iCloud.com / iCloud for Windows downloads | Often HEIC |
| Save to Files, then upload | HEIC |
| Google Photos / cloud backup apps | Often HEIC |
So if you changed how you back up or transfer photos — a new PC, a new cloud app, the Files app — you can suddenly start seeing HEIC files you never noticed before.
Why are my photos saving as HEIC on Android or Samsung?
Some Android phones, including many Samsung Galaxy models, offer a High efficiency pictures option in the camera settings. When it’s on, photos are saved as HEIF/HEIC to save space, just like on iPhone. Turning it off makes the camera save JPEG again — see the Android section of How to turn off HEIC.
How to get JPG instead
You have three choices, from least to most effort:
- Convert the photos you need. Keep HEIC on the phone and convert copies when sharing. Our HEIC to JPG converter works on your iPhone in Safari and saves the JPGs straight back to Photos, with no uploads. Other on-phone methods are in How to convert HEIC to JPG on iPhone.
- Let the iPhone convert on transfer. Go to Settings → Photos (on newer iOS: Settings → Apps → Photos) and set Transfer to Mac or PC to Automatic. Photos copied over a cable arrive as JPG.
- Shoot JPG from now on. Settings → Camera → Formats → Most Compatible. Photos will take about twice the storage. Full steps and trade-offs: How to turn off HEIC on iPhone.
Should you switch to JPG?
If you mostly view photos on Apple devices, keep HEIC — it’s simply the better format. If you constantly send photos to Windows users or upload them to sites that reject HEIC, switching or converting is worth it. Our comparison HEIC vs JPEG goes through the pros and cons.
