pdfxup

N-up PDF pages. N-upping means putting multiple pages onto one page by scaling and rotating them into a grid. More information: https://ctan.org/pkg/pdfxup.

• Create a 2-up PDF:
  pdfxup -o {{path/to/output.pdf}} {{path/to/input.pdf}}
• Create a PDF with 3 columns and 2 lines per page:
  pdfxup -x {{3}} -y {{2}} -o {{path/to/output.pdf}} {{path/to/input.pdf}}
• Create a PDF in booklet mode (2-up, and pages are sorted to form a book when folded):
  pdfxup -b -o {{path/to/output.pdf}} {{path/to/input.pdf}}
