Add page numbers to a PDF document

pdfnumbering builds on pypdf and fpdf2 to make it easy to stamp page numbers to a PDF document, and provides a convenient CLI tool to do so.

Install the published version from PyPI:

python -m pip install pdfnumbering

Or the development version from GitHub:

python -m pip install git+https://github.com/mikmart/pdfnumbering.git

Usage

Package

import sys

from fpdf import Align
from pdfnumbering import PdfNumberer
from pypdf import PdfWriter

INPUT_FILE = sys.argv[1]
OUTPUT_FILE = sys.argv[2]

numberer = PdfNumberer(
    first_number=1,
    ignore_pages=(),
    skip_pages=(),
    stamp_format="{} of {}",
    font_size=24,
    font_family="Helvetica",
    text_color=(0x18, 0x18, 0x18),
    text_align=Align.C,
    text_position=(0, -1),
    page_margin=(28, 28),
)
document = PdfWriter(clone_from=INPUT_FILE)
numberer.add_page_numbering(document.pages)
document.write(OUTPUT_FILE)
