If you've ever copied photos from an iPhone to a Windows PC, you've met the HEIC problem: Windows 10 and 11 don't open Apple's HEIC format out of the box. Microsoft offers "HEIF Image Extensions" in the Store, but it's unreliable — and it does nothing for the people you share the files with. The simplest fix is converting HEIC to JPG, a format everything opens.
The catch with most online converters is privacy: you're uploading personal photos to a stranger's server. The faymox HEIC converter runs entirely inside your browser using WebAssembly. Your photos are decoded and re-encoded on your own PC and never uploaded anywhere — you can even disconnect from the internet after the page loads and it still works.
Convert HEIC to JPG in 3 steps
- Open the faymox HEIC Converter in Edge or Chrome on your Windows PC.
- Drag in your
.heicfiles — or click to browse. Batch conversion is supported, so drop a whole folder's worth at once. - Choose JPG as the output format, hit convert, and download the JPGs. They land in your Downloads folder, ready to open, edit, or share.
FAQ
Why won't HEIC photos open on my Windows PC?
Windows doesn't ship the HEIF codec by default. The Microsoft Store extension works for some people but breaks often — and it does nothing for the people you share files with. JPG works everywhere with zero setup.
Is it safe to convert iPhone photos online?
With most converters your photos travel to a server. With faymox the conversion happens locally in your browser tab — open DevTools' network panel and you'll see zero uploads.
Will converting HEIC to JPG lose quality?
JPG uses lossier compression than HEIC, so the file gets a bit bigger or slightly softer at the same visual quality. For viewing and sharing the difference is invisible. Keep your original HEICs archived if you need pixel-perfect copies.
