Split/Tile A3 (landscape) pdf to A4 (portrait)

Question

How can I easily convert/split/tile every page of an PDF file which is A3/landscape to A4/portrait?

Answer 1

command line solution

1. Install pdfposter

   sudo apt-get install pdfposter

2. Use pdfposter

   pdfposter path/to/input.pdf path/to/output_splitted.pdf -m a4 -p 2x1a4

Answer 2

mutool poster -x 2 input.pdf output.pdf

Installation in Debian 10/Buster:

apt install mupdf-tools

For reordering the pages after splitting, you can use pdftk.

Answer 3

GUI solution

If the dimension (A4 instead of A3) is not important (as this is not important for viewing the file and can be easily adjusted while printing), you can use PDFsam (open source) which allows to rotate pages.
