Want to split, merge, rotate, and/or delete pages in your PDF files? Here’s a tool make it easy to do the job in Ubuntu Desktop.

It’s PDF Mix Tool, a free and open-source tool written in C++ and depends only on Qt 6 and PoDoFo.

How to Install PDF Mix Tool

Some Linux Distributions (e.g., Fedora, Arch Linux, openSUSE) have made the app package into system repositories.

For Ubuntu, users may choose to install it via either Snap or Flatpak package.

Option 1: Snap package

NOTE: The Snap seems not working good in my case in Ubuntu 24.04 with Xorg.

The Snap package is quite easy to install, simply launch App Center (or Ubuntu Software) then search and install ‘PDF Mix Tool’.

Option 2: Flatpak package

For choice, the app can be also installed via Flatpak package that works in most Linux.

• First, press Ctrl+Alt+T to open terminal and run command to install Flatpak daemon:

  sudo apt install flatpak

• Then, install the app as Flatpak package via command:

  flatpak install https://dl.flathub.org/repo/appstream/eu.scarpetta.PDFMixTool.flatpakref

  

After installation, just search for and launch it from either GNOME overview or start menu depends on your desktop environment.

If the app icon is not visible, either log out and back in, or try running the command below to start it from terminal:

flatpak run eu.scarpetta.PDFMixTool

Uninstall PDF Mix Tool

To uninstall the software package, either use Ubuntu Software (or App Center) for the Snap package.

Or run the command below to uninstall Flatpak package:

flatpak uninstall --delete-data eu.scarpetta.PDFMixTool

Optionally, you may also run flatpak uninstall --unused to remove useless runtime libraries.
