How does it work without uploading?
Most converters upload your photos to their servers, convert them there, then send them back. That means your personal photos — holidays, documents, family moments — are stored on a stranger's machine, even briefly.
This tool uses WebAssembly (WASM) — a technology built into every modern browser — to run the conversion code directly on your device. The conversion happens the same way a desktop app would: locally, privately, and instantly. We never see your files because they never travel anywhere.
The conversion logic is powered by heic2any (MIT license), an open-source library. This entire site's source code is also open source and available on GitHub for full transparency.

Common questions
Why can't I open HEIC files on Windows?
Apple introduced HEIC (High Efficiency Image Container) as the default photo format on iPhones in iOS 11. Windows doesn't include a HEIC decoder by default. You can either install Microsoft's free HEIF Image Extensions from the Microsoft Store, or convert the files to JPG using this tool.
Will converting reduce photo quality?
At 90% quality (the default), the difference is visually undetectable. You can crank it to 100% if you want lossless-equivalent output, though file sizes will be larger. HEIC photos are typically half the size of equivalent JPGs, so converted files will be larger than the originals — that's normal.
Does this work on iPhone or Android?
Yes. The tool runs in any modern browser. On iPhone you can share HEIC files directly from Photos, open them in Safari, and convert them. On Android, most photos are already JPG so you likely don't need this.
Is there a file size limit?
No server-side limit — your browser's available memory is the only ceiling. In practice, a 50-photo camera roll converts in under a minute on a modern phone or laptop.
What about EXIF data (location, date)?
EXIF metadata is preserved in the converted JPG. Your photo dates, camera info, and geolocation tags will remain intact.
