About this app

MuPDF viewer is an app for reading PDF, XPS, CBZ, and unprotected EPUB documents.

This is a slim version of the MuPDF app, which focuses on reading only. It does not support editing annotations or filling out forms.

Tapping on the left and right side of the screen will flip to the previous and next pages. Tapping in the middle of the screen will bring up or hide the tool bars.

The link button in the tool bar will toggle highlighting hyperlinks. When the links are highlighted they are also active and tappable. You can pinch to zoom in and out. When zoomed in, tapping will scroll to advance to the next screenful of content.

The toolbar also has a search button, and possibly a table of contents button.

The scrubber at the bottom of the screen will let you quickly go to any place in the document.

With the "Overview" system button, you can go back to the file chooser and open multiple documents at once.

Ratings and reviews

Finally, an app that allows proper PDF zoom on mobile. I tried apps including Adobe Acrobat Pro, Acrobat Reader, OneDrive, Xodo, Foxit, Word, Canva, and several more while adjusting settings with help from multiple AI platforms. Magnification was always capped well under 200 percent. MuPDF solved it. On my phone, I can zoom at least 500 percent with the same fine detail I see when using quality zoom on my laptop. This is exactly what I need to check image and print quality while on the go.

MuPDF is a fast and lightweight PDF reader, but it lacks several basic and important features. The search function does not work properly — it is case-sensitive, so searching in small letters does not find text written in capital letters, which makes searching very difficult. In addition, there is no proper share option to send PDF files directly from the app. Some versions also feel like the search feature is missing or incomplete.

Lightest viewer on the Play store! I've been looking for a thing like this for a long time. Every other app I tried is usually more complex than it should be and take longer than it needs to just for viewing a simple PDF. This is finally all I need in a very small footprint. It opens up incredibly quickly and views the PDFs in such a way that you can turn pages, like turning a page on a Kindle, to actually go to other PDFs in the same folder. The niftiest and most responsive thing I've seen.
