MuPDF

MuPDF is an open source PDF, XPS/OpenXPS, CBZ and EPUB document viewer.

MuPDF has support for all non-interactive PDF 1.7 features, and the toolkit provides a simple API for accessing the internal structures of the PDF document.

MuPDF supports interactive features:

• Text extraction
• Text search
• Hyperlinks
• Annotations
• Form-filling
• Digital signatures

MuPDF also features a competitive text reflow engine. This allows end-users viewing textual documents to reflow the width of the text to fit the screen width, thus allowing the end-user to read by simply scrolling down. In addition, MuPDF now offers “progressive rendering”. “Progressive rendering” allows end-users to view individual pages in documents with hundreds or thousands of pages more quickly.
