Stop iPhone Saving Photos as HEIC

If your photos keep arriving as .HEIC files that your Windows PC, older software, or a website upload form cannot open, the fix is a single settings change. Here is how to make your iPhone save JPGs instead — plus what you give up, and what to do with the HEIC files you already have.

Change the setting: Settings > Camera > Formats

1. Open Settings on your iPhone.
2. Tap Camera, then Formats.
3. Under Camera Capture, select Most Compatible.

That is it. From now on, photos are saved as JPG and videos as H.264 instead of HEIC/HEVC. The change applies to new captures only — it does not convert your existing library.

One nuance worth knowing: if you shoot in ProRAW or certain high-end modes, the camera settings can override this. For everyday photos, Most Compatible does what it says.

The tradeoff: larger files

HEIC is genuinely efficient — roughly half the file size of a comparable JPG — and it powers features like Live Photos and burst sequences without ballooning storage. Switching to Most Compatible means:

• Photos take more space. Expect JPGs around 2-4 MB where HEICs were 1-2 MB. On a 128 GB iPhone that adds up over thousands of photos.
• Videos get bigger too. H.264 files are noticeably larger than HEVC at similar quality.
• No visible quality loss. For normal viewing, sharing, and printing, the JPGs look just as good.

If storage is tight, the smarter move may be keeping HEIC and converting only the files you need to share — read on.

What to do with existing HEIC photos

The setting change does not touch your existing photos. For those:

• Convert to JPG with Formatly’s HEIC to JPG converter. It runs 100% in your browser, so your personal photos are never uploaded to a server — a meaningful difference from most “free” online converters. See our guide on converting HEIC to JPG without uploading for the full walkthrough.
• Share directly from the iPhone. When you AirDrop, message, or email a HEIC photo from iOS, Apple usually converts it to JPG automatically for the recipient.
• Understand the format before deciding: our HEIC vs JPG comparison lays out quality, size, and compatibility side by side.

Should you switch, or keep HEIC?

Switch to Most Compatible if:

• You regularly transfer photos to a Windows PC or older software.
• You upload photos to websites or forms that reject HEIC.
• You share originals with people on mixed devices and hate troubleshooting.

Keep High Efficiency (HEIC) if:

• Storage space matters more to you than compatibility.
• You live mostly inside the Apple ecosystem.
• You are comfortable converting the occasional file you need to share.

How to check which format you are using now

Not sure what your iPhone currently saves? The fastest check: take a photo, then transfer it to a computer or look at the file extension in the Files app. If it ends in .HEIC, you are on High Efficiency; if it ends in .JPG, Most Compatible is already active. You can also check retroactively in the Settings path above — the selected option is the one your next photo will use.

Quick recap

1. Settings > Camera > Formats > Most Compatible — new photos save as JPG.
2. Accept the tradeoff: bigger files, same visible quality, much better compatibility.
3. Convert existing HEICs with the HEIC to JPG tool — free, private, no uploads.

HEIC is the better format on paper; JPG is the better format in practice for anyone who shares photos beyond Apple’s walls. One settings change, and the compatibility headaches stop.
