Privacy & security
Your photos never leave this tab
Unheic is designed so that HEIC conversion cannot leak to a network. There is no upload API for images, and no account that could store them.
Client-side only
Decoding and JPEG encoding run in WebAssembly on your device. The HEIC bytes stay in browser memory until you download the JPG or close the tab.
No image servers
We do not operate a photo processing backend. There is nothing to intercept, no disk that could retain a copy, and no third-party CDN that receives your files.
Metadata stays with you
EXIF, GPS, and camera tags are read locally when Keep EXIF is on. If you turn it off, those tags are omitted from the JPG. Either way, metadata is not transmitted to us.
What we do collect
The static website may receive ordinary hosting logs such as IP address and requested URL. Those logs never include your photos.
