PDF Table of Contents Generator

The Quick Version

uvx --from git+https://github.com/sameerbajaj/pdf_toc_generator pdf-toc

The Problem

You download a 300-page PDF. There's a beautiful table of contents on page 5 — every chapter, every section, neatly listed with page numbers. But it's just an image. Click on "Chapter 12: The Important Part" and nothing happens. You're left scrolling through 300 pages trying to find page 247.

Meanwhile you can see the TOC right there mocking you. All that structure, completely unusable.

What This Does

The tool reads your PDF, finds the table of contents, and converts those entries into actual clickable bookmarks. Open the PDF sidebar and suddenly you can navigate the whole document properly.

Smart Page Matching

Here's the tricky part: the page numbers in a TOC often don't match the PDF's internal numbering. A book might have 20 pages of front matter with Roman numerals before "page 1" starts. This tool figures out the offset and matches entries to the correct pages.

Font-Based Detection

What if there's no printed TOC? The tool can detect headings by font size instead. Larger fonts usually mean chapter titles.

OCR Mode

For scanned PDFs where the text layer is garbage (or nonexistent), there's an OCR fallback. Slower, but it works.

Flat or Hierarchical

Choose whether you want nested bookmarks (chapters containing sections) or a flat list. Depends on the document.

Setup

Quickest way with uv:
