MuPDF
MuPDF is a lightweight PDF and XPS 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. It supports PDF 1.7 with transparency, encryption, hyperlinks, annotations, searching and more. It also reads OpenXPS documents. We don't support interactive features such as form filling, javascript and transitions. MuPDF is written modularly, so such features can be added on by integrators if they so desire.
