MuPDF is a small, fast, and yet complete PDF viewer that supports PDF 1.7 with transparency, encryption, hyperlinks, annotations, searching and more. It also reads XPS and OpenXPS documents.

The renderer in MuPDF is tailored for high quality anti-aliased graphics. It renders text with metrics and spacing accurate to within fractions of a pixel for the highest fidelity in reproducing the look of a printed page on screen.

MuPDF is available in Ubuntu repositories by default, but Canonical does not provide updates for this software. While Ubuntu Software Center provides the 1.6 (or older) release, the latest MuPDF 1.7a was released in last month with below changes:

  • Fixed bug that allocated too much memory when packing paths.
  • Fixed EPUB font scaling bug.
  • Fixed EPUB file type handling in viewers.
  • Improved tolerance for broken and unsupported CSS.
  • Added -z option to mutool clean.

Install MuPDF in Ubuntu:

1. Open terminal from the Dash, Application Menu, or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

mupdf-ppa

2. After adding the PPA, open Software Updater to automatically check for updates

Checking for Updates

After checking for updates, you’ll see MuPDF in the list available for upgrade if you have a previous version installed.

If you don’t have a previous release installed in your system, install it via Synaptic Package Manager or by running below command in terminal:

sudo apt-get install mupdf mupdf-tools

Once installed, open PDF/XPS files using MuPDF from their context (right-click) menu. For key bindings and other options, run man mupdf in terminal.

mupdf

To set MuPDF as default viewer, go to PDF file’s context menu -> Properties -> Open With tab -> select the viewer from list and click Set as default button.

MuPDF, a lightweight PDF and XPS viewer, has reached the 1.7 release. Here’s how to install or upgrade it in Ubuntu and Linux Mint.

MuPDF is a free and open-source viewer written in C. It focuses on speed, small code size, and high-quality anti-aliased rendering. Since the 1.2 release, MuPDF has optional support for interactive features such as form filling, JavaScript and transitions.

While Ubuntu repositories provide a very old version, the latest release, MuPDF 1.7, was released a few days ago with some new features and great improvements:

  • New HTML layout engine, and (DRM-free) EPUB viewer.
  • Reduced memory usage – reducing total memory use on some files by over 60%.
  • Better mouse wheel handling
  • Shift-space support
  • Add mutool pages option.
  • Mouse button control of presentation mode
  • many bug fixes.

For more, see the official release notes.

Install or Upgrade MuPDF:

For Ubuntu 12.04, Ubuntu 14.04, Ubuntu 15.04, and Linux Mint 13/17, the latest packages have been made into the PPA repository.
