What this does

Bookmarks Viewer reveals the outline (table of contents) embedded in a PDF — the same nested structure that PDF readers show in a sidebar. Useful for auditing structure or extracting a TOC.

When to use it

  • Auditing whether a long PDF has proper navigation structure
  • Generating a written table of contents from a book or report
  • Quickly understanding the structure of an unfamiliar document

Frequently asked

What if the PDF has no bookmarks?

You'll see a "No bookmarks" message. Not every PDF has them — they're set by the original author.

Can I download the outline?

Yes — export as a plain .txt file with indented entries.
