How to stop your iPhone taking HEIC photos

There are two different iPhone settings tangled up in every “how to turn off HEIC” answer, and they do different jobs. One changes what the camera records. The other changes what the phone hands over when you plug it into a computer. Understanding both takes three minutes and saves you from converting files forever.

Setting 1: make the camera shoot JPEG

Settings → Camera → Formats → choose “Most Compatible.”

That’s the whole move. From the next shot onward, your iPhone saves JPEG instead of HEIC. “High Efficiency” is the HEIC setting; “Most Compatible” is JPEG. (On recent iOS versions the Camera settings live under Settings → Camera; if your Settings app shows an Apps section, look for Camera inside it.)

Three things to know before you flip it:

1. It only affects future photos. Everything already shot in HEIC stays HEIC — that backlog is what our bulk converter is for.
2. It costs storage. JPEG runs materially larger than HEIC for the same shot — the common rule of thumb says up to about twice the size, varying by scene. On a 128 GB phone with a big library, that’s not nothing. If storage is tight, consider leaving the camera on High Efficiency and using Setting 2 instead.
3. Some capture modes may still produce HEIC-family files. Certain advanced modes (burst sequences, some computational formats) have their own storage behavior. For everyday photos, Most Compatible means JPEG.

Who should use this setting

People whose photos routinely leave the Apple ecosystem the moment they’re taken: you shoot on iPhone but work on Windows, you upload photos to web forms for work, you share to mixed groups constantly. If every photo you take makes the HEIC-to-JPG trip anyway, shooting JPEG in the first place is strictly simpler.

Setting 2: convert during USB transfer

Settings → Photos → scroll to “Transfer to Mac or PC” → choose “Automatic.”

This one leaves your camera shooting space-efficient HEIC but tells the phone: when a computer imports photos over the cable, hand over a compatible format if the computer needs it. Your on-phone library stays small; the Windows machine receives files it can open.

The honest fine print, learned from many confused forum threads:

• “Automatic” means the phone decides. Around iOS 17, Apple refined the behavior: if the receiving system can handle HEIC, the phone may transfer the original HEIC rather than converting. That’s clever, except when the system can technically store the file and the program you care about still can’t open it — which is how people end up with HEICs on a PC despite setting Automatic. If that happens to you, the reliable fallback is converting the files themselves: drop them here.
• “Keep Originals” is the other option — the phone always transfers exact original files. Choose it deliberately if you want true originals (for archiving or editing); pair it with a converter for the files that need to open elsewhere.
• This setting does nothing for AirDrop, email, chat apps or cloud drives. Each of those paths makes its own format decisions (AirDrop between Apple devices keeps HEIC; many chat apps convert to JPEG and recompress). It governs the USB import path only.

Which setting should you change?

There’s no wrong answer, only mismatched defaults. The iPhone’s out-of-the-box configuration (High Efficiency + Automatic) is genuinely good for people inside the Apple ecosystem; it’s everyone straddling ecosystems who needs to pick a lane.

“I changed the setting — why are there still HEICs?”

The four usual suspects:

1. Old photos. The setting isn’t retroactive; your existing library is unchanged.
2. Other people. Photos shared to you from other iPhones arrive in whatever format they sent — often HEIC.
3. The Automatic nuance above. The phone judged the destination HEIC-capable and sent originals.
4. Renamed files. Some apps rename HEIC files to .jpg without converting them, which produces “JPGs” that won’t open. Our converter detects this by reading the file’s real contents and tells you what it found.

For all four, conversion-on-demand is the safety net, and doing it locally in your browser means the photos never take a detour through someone’s server.

The bigger picture

Apple isn’t wrong that HEIC is the better format — it holds more image in fewer bytes. The industry just never finished the compatibility story around it, a decade in (here’s the full state of play). Until it does, these two settings plus a private converter cover every practical case: shoot what suits your storage, transfer what suits your computer, and convert whatever’s left over.
