How to Create PDF
Table of Contents
Automatically

Upload a PDF and get it back with a bookmark outline and a clickable contents page written in — your original pages untouched. Perfect for technical manuals, research papers, e-books, and any long document that is painful to navigate.

4 Simple Steps to Add a Table of Contents to a PDF

From upload to a bookmarked, clickable document — checking the page numbers as you go

1

Upload Your PDF Document

Select a PDF file from your computer. The free plan handles files up to 10MB, Pro up to 100MB, and Enterprise up to 500MB.

  • Drag and drop or browse to select your file
  • Works with any PDF that has a text layer
  • The file is parsed in your browser, not uploaded
  • Free account gets you started

AI Analyzes Document Structure

Our advanced AI scans your PDF in seconds, identifying headings, subheadings, and document hierarchy automatically.

  • Machine learning algorithms detect text structure
  • Recognizes various heading styles and formats
  • Reads scanned PDFs that already carry an OCR text layer
  • Every detected heading gets a confidence score

Check Page Numbers Against the Live Preview

Your document renders right beside the detected headings. Click any heading and the preview jumps to that page, so you can confirm the page number is correct before you export anything.

  • Your actual PDF pages, rendered beside the contents
  • Click a heading to jump the preview straight to that page
  • Edit titles, page numbers, and hierarchy levels inline
  • On a phone, the contents and the document become tabs

Get Your PDF Back With Bookmarks

Export writes a bookmark outline and a clickable contents page into your own PDF. Your original pages come back untouched — it is your document, now navigable.

  • A real PDF outline — the bookmark panel readers show in the sidebar
  • A contents page added at the front, where every row is a working link
  • Your original pages are preserved exactly as they were
  • Word, plain text, and JSON export the contents list on its own

Why Use Automated PDF Table of Contents Generation?

Stop creating table of contents manually and embrace the power of AI automation

Save Hours of Manual Work

Adding bookmarks to a 300-page PDF by hand takes an afternoon. Upload it, check the page numbers against the preview, and export the finished document in seconds.

Supports Accessible Navigation

The outline is written into the document itself, and a bookmarked hierarchy is what screen readers use to move through a long PDF — supporting your WCAG 2.1 and Section 508 work.

AI-Powered Accuracy

Advanced machine learning ensures accurate detection of document structure and heading hierarchy.

Frequently Asked Questions

Common questions about automatic PDF table of contents generation

Does automatic TOC generation work with scanned PDFs?

It works with scanned PDFs that have already been through OCR and carry a text layer — the AI reads that text and identifies structure normally. Purely image-based PDFs with no embedded text are not supported yet, so run those through an OCR step first.

How accurate is the automatic heading detection?

Detection quality depends on how consistently the source document is formatted — clean, distinct heading styles detect best. Each entry carries a confidence score, and because your document renders beside the contents, you can click any heading and see the page it points at before exporting.

Does this add real bookmarks to my PDF, or just make a separate file?

Real bookmarks, written into your own PDF. The export contains a proper PDF outline — the tree your reader shows in its bookmarks sidebar — plus a contents page inserted at the front where every row is a clickable link to that section. You are not downloading a separate list of headings; you are downloading your document with navigation added.

Does it change my original pages?

No. Your pages are carried through unmodified — the only structural change is the contents page added at the front, which shifts the page numbering by a page or two, and the contents page accounts for that shift. Nothing in your content is rewritten, recompressed, or reflowed.

Can I customize the generated table of contents?

Yes. You can edit titles, adjust page numbers, change hierarchy levels, reorder entries, and remove unwanted items before exporting. The heading hierarchy you set is the nesting that appears in the bookmark tree.

What can I export?

The main export is your PDF with a bookmark outline and a clickable contents page written into it. You can also export the contents data on its own as Word, plain text (.txt), or structured JSON — those give you the heading list for use elsewhere, not your document.

What does the free plan include?

The free plan links the first 25 headings — those get bookmarks and clickable contents rows. Any headings past 25 are still printed on the contents page, just without links, and the exported document is always complete: we never hand back a truncated copy of your file. Pro and Enterprise link every heading.
