HEIC vs JPG — Apple Format vs Universal Standard
Understand why your iPhone uses HEIC, how it compares to JPG, and when you need to convert HEIC to JPG for compatibility.
Quick answer: why are my photos HEIC and not JPG?
Your iPhone camera is set to High Efficiency, the default since iOS 11, so it saves photos as HEIC, which takes about half the space of a JPG at the same quality. Switch to Settings > Camera > Formats > Most Compatible to shoot JPG from now on. Photos you already took stay HEIC, so convert them to JPG when a website or PC will not open them.

Why Does My iPhone Use HEIC?
HEIC is Apple's default format because it offers roughly 50% better compression than JPG at the same visual quality. This means your iPhone photos take up half the storage space while looking just as good.
However, HEIC isn't universally supported. According to caniuse.com/heif (accessed September 17, 2026), native in-browser HEIC decoding is exclusive to Safari. Chrome, Firefox, and Edge do not decode HEIC files natively. In addition, Windows PCs require the HEIF Image Extensions to open HEIC files in desktop apps, making conversion to JPG essential when sharing or uploading to web forms.
How to Make Your iPhone Save JPG Instead of HEIC
- Open Settings and tap Camera.
- Tap Formats.
- Choose Most Compatible. New photos are saved as JPG (and new videos as H.264).
This only changes photos you take from now on. For photos already in your library, open Settings > Photos and set Transfer to Mac or PC to Automatic so iOS hands a computer JPG copies over USB, or convert individual files with the HEIC to JPG converter. New to the format? Read what a HEIC file is.
Keep HEIC format when:
- 📱 Sharing between Apple devices (AirDrop, iMessage)
- 📱 Saving storage space on your iPhone or iPad
- 📱 Sending to other iPhone or Mac users
- 📱 Keeping original quality for photo editing
- 📱 Storing in iCloud Photos
