You can find also a nice explanation of these licenses under https://itsfoss.com/open-source-licenses-explained/

We want OpenPDF to consist of source code which is consistently licensed with the LGPL and MPL licences only. This also means that any new contributions to the project must have a dual LGPL and MPL license only.



OpenPDF is open source software with a LGPL and MPL license. It is a fork of iText version 4, more specifically iText svn tag 4.2.0, which was hosted publicly on sourceforge with LGPL and MPL license headers in the source code, and LGPL and MPL license documents in the svn repository. Beginning with version 5.0 of iText, the developers have moved to the AGPL to improve their ability to sell commercial licenses.

OpenPDF ancestors in GitHub (in fork order):

  1. @rtfarte / OpenPDF - parent of LibrePDF/OpenPDF
