Open Source Users

Artifex is committed to supporting the Open Source community as a whole, and we hope our AGPL license versions of MuPDF provide valuable contributions to your project.

Practically speaking, we do not have the time or resources to provide direct technical support or respond to the needs of individual free users. However, there are various forums available where you may find answers to questions you may have. Our software is widely used all over the world, and there are many people in the community who will help you.

If you are using an AGPL licensed version of MuPDF, we recommend exploring the following sources for answers to your questions:

  • Stack Overflow – This website has a small but active community involved with MuPDF, as well as PostScript and PDF. Questions raised here will often get a good response.
  • Bug Tracker – You can report bugs or raise enhancement requests to our bug tracking system at http://bugs.ghostscript.com. We can’t promise to fix every end-user problem, but we will review them all.
  • IRC channel – MuPDF developers can be found on the #mupdf IRC channel on irc.freenode.net. Questions asked here will usually get a response, though time zone differences can mean there are periods when nobody is available.) The channel is logged.
