Open Source Licenses

UtilBear runs its tools in your browser, so the open source components below are downloaded to your device and run there. Nothing on this page is sent to us.

heic-to 1.5.2

Decodes HEIC and HEIF photos, the format an iPhone saves by default. It wraps libheif 1.22.2, which does the actual decoding, and which in turn carries libde265 for the HEVC frames inside the file. Used by the HEIC converter, and downloaded only after you pick a file.

License: LGPL-3.0, for all three (full text, which applies on top of the GNU GPL v3). Source code: https://github.com/hoppergee/heic-to.

We serve it unmodified, as a separate file at /vendor/heic-to-1.5.2.min.js, and never merge it into our own code. That is what the LGPL asks for, and it is what makes the library replaceable: take the source above, build your own version, serve this page with your build at that path, and the converter will use it instead of ours.

client-zip 2.5.0

Packs converted files into a ZIP archive on your device, so a batch can be saved in one click.

License: MIT. Source code: https://github.com/Touffy/client-zip.

Everything else

The rest of the site is our own code, built with Astro (MIT). The counters, the WebP converter and the image encoding all use features built into your browser and carry no third-party code at all.
