Found this on stackoverflow: https://stackoverflow.com/questions/68903835/how-to-draw-a-shape-inside-a-pdf-with-python

import fitz

Open the pdf

doc = fitz.open(‘./test.pdf’) for page in doc: # For every page, draw a rectangle on coordinates (1,1)(100,100) page.draw_rect([1,1,100,100], color = (0, 1, 0), width = 2)

Save pdf

doc.save(‘./your-route/name.pdf’)

Seems like it has a solid chance of working.
