Convert HEIC to JPG — without uploading your photos
HEIC is the format iPhones use to save photos. It compresses better than JPG, but plenty of apps, websites, and older software still refuse to open it. This tool converts HEIC to JPG entirely on your own device: the conversion runs in your browser using WebAssembly, so your photos are never uploaded to any server. That matters for photo libraries in particular — personal pictures should not have to make a round trip through someone else’s cloud just to change format.
How it works
- Drop your .heic files below (or click to pick them). You can select several at once.
- Adjust JPG quality if you want — 80 is a good default for photos.
- Each converted JPG downloads directly from your browser’s memory.
Frequently asked questions
Are my photos uploaded anywhere?
No. The converter runs inside your browser using WebAssembly (the same technology that powers in-browser games and photo editors). Your files are read locally, converted locally, and never transmitted. You can verify this in your browser’s network tab, or even switch off your connection after the page loads.
Why does my iPhone save photos as HEIC?
HEIC (High Efficiency Image Container) stores photos at roughly half the file size of JPG at similar quality, so Apple made it the default in iOS 11. You can make your iPhone shoot JPG instead under Settings → Camera → Formats → Most Compatible.
Does converting lose quality?
JPG is a lossy format, so there is a small quality trade-off controlled by the quality slider. At quality 80–90 the difference is invisible for typical photos. The original HEIC file on your device is untouched.
Is there a file size or count limit?
No hard limit — processing happens on your machine, so the practical limit is your device’s memory. Hundreds of photos work fine on a typical laptop.
