Minimalist viewer for PDF, XPS, CBZ, unprotected EPUB, and FB2 documents
About this app
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.
Tapping on the left and right side of the screen will flip to the previous and next pages. Tapping in the middle will bring up or hide the tool bars. A long tap will toggle highlighting of links. When the links are highlighted they are also active and tappable.
You can pinch to zoom in. When zoomed in, tapping will scroll to advance the next screenful of content.
In the toolbar there is a button to show the table of contents, if the document has one. In EPUB and FB2 documents, there is also a menu item to pick the font size. The scrubber at the bottom allows you to quickly jump to a given page in the document.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.artifex.mupdf.mini.app is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.27.1a is the last build before it. Android will not install an older version code over a newer one, so you must uninstall MuPDF mini first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of MuPDF mini, and a listing is removed when the evidence for it stops holding up.
