Media worker source code
The media worker that runs audio, video, PDF to Word and PDF to Excel conversions uses PyMuPDF, which is licensed under the GNU Affero General Public License v3.0. The worker is therefore released under the same licence, and its complete source code is available to everyone who uses this service.
