Your photos never leave your device

What happens to your files

• Your device converts the photos. The page sends nothing.
• The page has no ads, no account and no cookies.
• If the page has an error, it sends an error report to the server. The report has no photo, no file name and no file data.
• The page removes the location (GPS) from your photos by default. You can choose to keep it.

Licences and credits

You can replace the LGPL files

The libheif code is in three separate files. We did not change them. They are at /vendor/libheif/1.23.5/libheif.js, /vendor/libheif/1.23.5/libheif.wasm and /vendor/libheif/1.23.5/LICENSE. You can replace them with your own build of libheif.
