pdftool.py is a new tool I developed. This version has only one command: ui (incremental updates).

With this command, one can check if a PDF has incremental updates, and then select different versions of this PDF with incremental updates.

A PDF with incremental updates, is a PDF that has been modified by appending changes to the document at the end of the PDF file, without modifying the original content.

Here is a video explaining incremental updates and the use of my tool.

I reference 2 blog posts in the video: “Solving a Little PDF Puzzle” and “Shoulder Surfing a Malicious PDF Author“.
