MuPdf

MuPDF is a lightweight PDF and XPS interpreter that offers all the interactive features of PDF.

It is a small, fast and complete interpreter/renderer suited perfectly for mobile, ePub and other embedded applications.

  • Support for PDF 1.7 transparency and encryption
  • Support for interactive features – hyperlinks, annotations, search, form filling, javascript and transitions.
  • Reads XPS and OpenXPS documents
  • Written modularly – features can be added on by integrators as desired.
