PdfJumbler simple tool to rearrange, merge, delete, and rotate pages from PDF files.
PdfJumbler requires a Java Runtime Environment (JRE), version 11 or above. You can download one at https://adoptopenjdk.net/.
Windows users can simply download and run the installer (setup-pdfjumbler.exe), which creates a start menu entry for PdfJumbler.
For Ubuntu (and probably Debian), you can use this command to install PdfJumbler:
curl -L https://raw.githubusercontent.com/mgropp/pdfjumbler/master/setup/ubuntu/install.sh | bash
Alternatively, there is a runnable jar file (just double-click), pdfjumbler.jar.
The user interface is actually rather simple: pages can be moved around using drag&drop (or the keyboard, see below), and for more complex operations there's a second page list available to the left (just pull it out).
PdfJumbler accepts pdf files as command line arguments.
Several settings can be changed using Java system properties:
pdfjumbler.editor: sets the editor plugin (if installed; previous plugins are no longer supported)
pdfjumbler.renderer: sets the renderer plugin (if installed; previous plugins are no longer supported)
user.language: sets the program language (in case auto-detection doesn't work).
