Why HEIC won't open on Windows
When you send photos from an iPhone, they often arrive as HEIC — Apple's efficient photo format. Windows doesn't decode HEIC out of the box; double-click one and you'll usually be pushed to buy the HEIF Image Extensions codec from the Microsoft Store. The simplest fix is to convert the files to JPG, which every version of Windows opens natively.
The Unfuss HEIC to JPG converter decodes HEIC in your browser using JavaScript, so it works in Edge and Chrome on Windows 10 and 11 with nothing to install — and your photos are never uploaded.
Step by step on Windows
- Open Edge or Chrome and go to unfuss.app/heic-to-jpg.
- Drag your .heic files from File Explorer onto the drop zone (or click to browse).
- Wait a moment — each photo is decoded and re-saved as a JPG on your PC.
- Download each JPG, or grab them all as a single ZIP.
Convert, don't install
Installing the codec lets you view HEIC in Windows Photos, but many programs still won't accept the format for upload or editing. Converting to JPG once gives you files that work everywhere — email, Office, printers, and any website. Need them smaller too? Run the JPGs through the image compressor.
Frequently asked
Why won't HEIC files open on Windows?
HEIC is Apple's photo format. Windows doesn't decode it out of the box — you'd normally need the HEIF Image Extensions codec from the Microsoft Store. Converting to JPG avoids that entirely.
Do I need to install a codec or app?
No. The converter decodes HEIC in your browser using JavaScript, so it works in Edge and Chrome on Windows with nothing to install.
Are my photos uploaded?
No. The conversion runs on your PC inside the browser. Your photos never leave the computer.
Can I convert many HEIC files at once?
Yes. Drop a whole folder of .heic files and download all the JPGs together as a ZIP.
