Credits and licences

This page says what on the site is ours, how you may use the tools, and whose open-source work we build on. Thank you to everyone who made these tools possible.

Other people's libraries we use

The web tools build on the open-source works below. They are under their authors' own licences, which the text above does not limit. The full licence of each is at the link at the end of its row. We use every file as its author published it, without changes to the code, except where noted.

About libheif (LGPL)

The HEIC opener uses libheif-js, which is under the LGPL-3.0 licence. We have not changed the file: it is used as its author published it, kept as a file of its own that is loaded only on the HEIC conversion page. Its name, origin and hash are in the README of that folder. The original source code is available from the libheif and libheif-js projects.
