If you’ve ever tried to upload an iPhone photo and been told the file isn’t supported, you’ve met HEIC. Here’s what it is and how to turn it into a universally-accepted JPG without handing your photos to a random website.
What is HEIC, and why does my iPhone use it?
HEIC (High Efficiency Image Container) is the format Apple uses by default to save photos. It uses modern compression to store high-quality images at about half the file size of JPG. That’s great for saving space on your phone — but not so great when you try to open the photo on a Windows PC, upload it to an older website, or share it with someone on a different device.
The quick fix on your iPhone
If you’d rather avoid HEIC entirely, you can tell your iPhone to shoot in JPG:
- Open Settings → Camera → Formats.
- Choose Most Compatible.
New photos will be saved as JPG. This won’t convert photos you already have, though — for those, you’ll need a converter.
Converting existing HEIC photos to JPG
There are plenty of online HEIC converters, but most of them upload your photos to a server. Your personal pictures — which might include family, documents or IDs — end up on someone else’s computer. That’s an unnecessary privacy risk.
A better approach is to convert in your browser, where the photo never leaves your device. Our HEIC to JPG converter does exactly that:
- Open the converter and drop in your
.heicfiles (you can do several at once). - Choose JPG as the output.
- Click convert — it happens instantly on your device.
- Download your JPGs. No upload, no sign-up, no watermark.
Prefer PNG instead? Use the HEIC to PNG converter.
Will I lose quality?
Converting HEIC to JPG involves re-encoding the image, and JPG is a lossy format, so there is a small quality trade-off. In practice, at high quality settings the difference is invisible for everyday photos. If you need to keep the file small for an upload limit afterwards, the Compress Image tool lets you target an exact size.
Why convert locally?
- Privacy: your photos never get uploaded.
- Speed: there’s no upload wait — conversion is instant.
- Free: no account and no watermark.
Summary
HEIC saves space on your iPhone but causes compatibility headaches everywhere else. Switching your camera to “Most Compatible” prevents new HEIC files, and a private, in-browser HEIC to JPG converter handles the photos you already have — without ever uploading them.
