Create Clickable Table of Contents for Your PDFs

Create a clickable PDF table of contents in seconds — AI detects every heading and builds structured navigation automatically.

Create a clickable PDF Table of Contents in seconds without manual bookmarking. Upload any document and our AI Table of Contents generator automatically detects every heading and subheading — building a structured, nested outline with working links that works in any PDF reader. Publishers, consultants, legal teams, and researchers save twenty minutes per document while getting professional navigation that actually works. Our heading detection handles irregular formatting and scanned documents where simple PDF libraries fail completely.

PDF TOC Generator finds headings the way a layout actually signals them, then checks that reading with a language model before committing to a structure. A first pass analyzes font size, weight, and spacing across the whole document and ranks every line by how strongly it looks like a heading — this catches structure even in scanned or inconsistently formatted PDFs where a simple text-search or fixed style rule would miss it.

Those ranked candidates, together with supporting signals such as total page count, paragraph density, and the document's overall font range, are then passed to a language model. The model decides which candidates are genuine section headings rather than false positives — an all-caps label, a pull quote, a running header — and assigns each one a level (H1, H2, H3...) to build a properly nested outline rather than a flat list.

The validated outline becomes clickable PDF bookmarks in your reader's navigation panel, and the tool inserts a matching table-of-contents page at the front of the document. Nothing about the body text, images, or layout is modified — only navigation is added, and the file is not retained after you download it.
