PDF Mix Tool For Linux

PDF Mix Tool is a free and open-source, Linux-only application that provides a simple GUI for performing basic editing operations on PDF files.

Before we talk about what this app can actually do, please note that you need to install an xdg-desktop-portal backend in for the app to work as intended. You can choose between xdg-desktop-portal-gtk or xdg-desktop-portal-kde based on your OS' DE.

With the help of PDF Mix Tool you can merge two or more files with the option to specif the number of pages for each of them, rotate pages within a PDF, composite more pages into a single one. You can also combine all the operations mentioned above.

Other things that PDF Mix Tool can do include mixing files by alternating their pages, generating booklets, adding white pages to PDF files, delete or extract pages, as well as edit the PDF document information.

Clearly, PDF Mix Tool is not the most feature-rich, or the most stylish-looking application of this sort out there. Nevertheless, it gets the job done, just as long as you have a bit of patience to learn how it works.

The way PDF Mix Tool works is very similar to other apps of this sort. You load the PDF file(s) by clicking the "Add PDF file" button, you double-click on the entry of a file to edit its properties, and generate the output file by clicking the "Generate PDF" button at the bottom.

To set page filters, you'll have to use the following format: "1-5, 7-10, 15, 19" or "1-5 7-10 15 19." To include the entire file, you have to leave the field blank, and you can also use overalapping intervals so that the pages will be replicated.

PDF Mix Tool might not be the perfect answer for everyone looking to edit their PDF files, but it's definitely a good application (despite being a bit clunky on our testing machine running Ubuntu 22.04).
