About MuPDF mini
MuPDF Mini Viewer is a minimalist Android app that uses the MuPDF library to view PDF, XPS, CBZ, unprotected EPUB, and FB2 documents. This is a minimalist version of the MuPDF app, which focuses on reading only. It does not support editing annotations or filling out forms. The app will start with a file picker showing the contents of the external storage directory. Only files that it can open will be listed. Each document you open will start its own activity, so you can view many documents at once. Use the Overview system button to switch between the file picker and any open documents and other activities you have running.
Privacy and F-Droid
F-Droid builds MuPDF mini from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
No anti-features flagged on the latest F-Droid build.
