This is in low maintanance mode.
I don't use it nowadays except for the rare cases in which I have to add page numbers to PDF files.
For all other PDF manipulation I suggest you use pdfarranger.

PDFsak (PDF Swiss Army knife) is an utility to manipulate PDF files.
The previous name of the project (as of 2021-10-10) was "pdftools".
It allows you to:
- Merge
- N-up pages (put more than one input page into a single output page)
- Trim pages
- Extract pages
- Rotate pages
- Swap pages
- Delete pages
- Create handouts
- Add text (like page numbers)
- Remove owner protection (the one which allows you to open the file without a password, but not to print, annotate or copy from it)
- Remove metadata
- Simulate Adobe Acrobat Clearscan: vectorize the text to improve quality and readability
- Add watermarks or images
- And more
PDFsak has been tested on Windows and Linux (Fedora).
It should work also on macOS, although it has not been tested on this platform.
