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
• 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.
Ratings and Reviews
Very Fast PDF Reader
This is one of the fastest PDF readers I've used on iOS. There are only two things that keep it from being 5 stars for me:
1. There are touch zones to the right and left of each PDF page that move you back and forth between pages. This can sometimes get in the way and I would like to see an option to either disable it or tweak the settings so that the touch zones stay farther to the outside of the document.
2. The other thing I'd like to see is the ability to rename the PDF documents.
I don’t use the Books store or need most of its functionality, love that this can take its place! Nothing like a basic, open source, GPL licensed alternative!
One of the few free EPUB readers left.
One of the few free EPUB readers that lets you add books via iTunes app on your desktop Mac.
Excellent all around. No ads. No subscriptions. Nada!
