# License

## Open Source

MuPDF is licensed under the GNU AGPL.

This is a complex license that allows you to use MuPDF to build your own projects for free, with no warranty and no support. It imposes many conditions on users, including the need to release the full source code for systems built with it.

Please ensure that you can comply with the conditions of the AGPL license.

See Artifex licensing guide if you have questions.

## Commercial

For those users that cannot (or do not want to) comply with the terms of the GNU AGPL, it is also offered under a commercial license. This completely frees users from the complexities imposed by the GNU AGPL.

Please contact us if you require a commercial license.

This software is distributed under license and may not be copied, modified or distributed except as expressly authorized under the terms of that license.
