OSTEP Book PDF Downloader

A program that scrapes the individual chapters of the OSTEP book from the official website, merges them, and adds an embedded table of contents (so you can jump to specific chapters in the table of contents section of your PDF viewer), including sub-chapters (e.g. sub-chapter 19.1).

Install uv and run

uv run main OSTEP.pdf

to have the the generated PDF saved to ./OSTEP.pdf.

Personally, I found the book a little too tall to read comfortably on a tablet without wasting space, so I added an option to crop the book to a 4:3 aspect ratio, which you can enable with:

uv run main --crop OSTEP-cropped.pdf

You can some basic tests with

uv run pytest
