a lightweight PDF, XPS, and E-book viewer

The renderer in MuPDF is tailored for high quality anti-aliased graphics. It renders text with metrics and spacing accurate to within fractions of a pixel for the highest fidelity in reproducing the look of a printed page on screen. MuPDF is also small, fast, and yet complete.

MuPDF supports PDF 1.7 with transparency, encryption, hyperlinks, annotations, searching and more. MuPDF also reads many other document and e-book formats, such as XPS, OpenXPS, CBZ, EPUB and FictionBook 2.

MuPDF is written modularly, so features can be added and removed by integrators if they so desire.

Since the 1.2 release of MuPDF, we have optional support for interactive features such as form filling, javascript and transitions.
