What you can do here
See what this workflow does, why local handling matters, and where it fits into practical PDF work.
Capabilities
- Detect headings and levels automatically
- Generate interactive PDF bookmarks (outlines)
- Create a physical Table of Contents page with clickable links
Why local matters
- Long documents like books, financial reports, or legal filings are highly sensitive. A 0-byte upload policy guarantees complete confidentiality.
- Parsing large multi-hundred page documents is faster when done locally, avoiding massive upload times.
- A local-first TOC generator parses and updates documents directly in the browser via WebWorker heuristics in just a few seconds.
Use cases
- Add bookmarks and a clickable TOC page to a corporate report
- Structure scanned books and manuals for easier navigation
- Prepare legal and financial binders with nested outline levels
TOC & Bookmark intents covered here
This page serves as the main destination for users looking to organize PDF navigation, create clickable directories, or build outline levels.

Questions users ask before they open this workflow
How does the heading detection work?
The tool uses smart font-size heuristics to identify potential headings and nest them into levels (H1, H2, H3) automatically, which you can easily edit in the review panel.
Does this create physical pages or sidebar bookmarks?
Both. You can generate standard PDF bookmarks (accessible in any PDF viewer sidebar) and/or insert a physical Table of Contents page at the beginning of the file.
What languages are supported?
All major languages, including Baltic, Cyrillic, and Latin alphabets, are supported with embedded font styling for the physical TOC page.
