Why We're the Best Free PDF TOC Generator
Advanced features that set us apart from the competition
Your PDF Back, Not a Separate File
The export writes a real bookmark outline and a clickable contents page into your own document. Your original pages come back untouched
See the Document While You Edit
Your PDF renders beside the detected headings. Click one and the preview jumps to that page, so you can check the page number before exporting
Seconds, Not Hours
Generate a professional table of contents in seconds using AI structure analysis, instead of bookmarking a long PDF by hand
Works With Any Text-Based PDF
Handles technical manuals, research papers, e-books, and reports — up to 10MB free, 100MB on Pro, and 500MB on Enterprise
Supports Accessibility Work
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 efforts
Confidence Scores on Every Entry
Each detected heading comes with a confidence score, so you can spot and fix the handful of entries worth a second look
Free Plan to Start
Drop in a PDF and see the result before creating anything — sign in for AI heading detection, and upgrade only if you need bigger files or batch processing
Contents Data Too, If You Need It
Alongside the navigable PDF, you can export the heading list on its own as Word, plain text, or structured JSON for use in other tooling

Frequently Asked Questions
Everything you need to know about our free PDF TOC generator
Is the PDF table of contents generator really free?
Yes. The free plan costs nothing and has no hidden fees. It covers PDFs up to 10MB, 5 documents a month, and gives you the real output: your PDF back with bookmarks and a clickable contents page. You can try it without an account — signing in switches heading detection from pattern matching to the AI model, which is noticeably better on complex layouts.
What is the catch on the free plan?
Links, not pages. Free links and bookmarks the first 25 headings; anything past that is still printed on the contents page, just without a link. The exported document itself is always complete — we never hand back a truncated copy of your file. Pro and Enterprise link every heading.
Does it add real bookmarks to my PDF?
Yes. The export contains a proper PDF outline — the bookmark tree your reader shows in its sidebar — written into your own document, plus a contents page inserted at the front where every row is a clickable link. Your original pages are preserved unmodified.
How do I know the page numbers are right?
Your document renders beside the detected contents. Click any heading and the preview jumps to that page, so you can confirm the number before you export rather than discovering a bad link afterwards. On a phone the contents and document become tabs.
What do I get on the free plan versus a paid plan?
Free covers single documents up to 10MB, 5 a month, with the first 25 headings linked. Pro ($29/month or $228/year) links every heading, raises the limit to 100MB, and adds batch processing up to 20 files, priority processing, and custom branding on exports. Enterprise ($99/month or $948/year) goes to 500MB with unlimited batch processing.
What kinds of PDFs does it work with?
Any PDF that contains a text layer — technical manuals, research papers, e-books, reports, and policy documents. Scanned PDFs work as long as they have already been run through OCR. Purely image-based PDFs with no embedded text are not supported yet.
Can I use this for commercial or business purposes?
Absolutely! Our free tool can be used for commercial and business purposes. Many teams use it for technical documentation, reports, and client deliverables. Pro and Enterprise plans are available when you need larger files or batch processing.
