PDF Structure & Navigation Tools
Six tools built around one thing: a PDF's bookmark tree — reading it, writing it, splitting a document along it, or building one from scratch. Each does one job distinctly; this table is the fastest way to find the right one for what you have.
| Tool | Input | Output | Best for | |
|---|---|---|---|---|
PDF TOC Generator | Any PDF (with or without bookmarks) | PDF with a new bookmark outline + printed contents page | Documents that don't have structure yet — AI detects headings from the text. | |
Bookmark Editor | PDF with existing bookmarks | The same PDF, bookmarks fixed | Bookmarks that already exist but are wrong, misnamed, or badly nested. | |
Split by Bookmarks | PDF with existing bookmarks | ZIP of one PDF per chapter/section | Turning one large PDF into many smaller files along its existing structure. | |
Outline Extractor | PDF with existing bookmarks | Markdown, JSON, CSV, text, or HTML — no PDF | Getting the structure out as data for a script, spreadsheet, or LLM prompt. | |
Bookmarks to TOC | PDF with existing bookmarks | The same PDF plus a printed, clickable contents page | Bookmarks that are already correct but have no printed contents page. | |
Batch Add Bookmarks | Many PDFs sharing a structure | ZIP of every file, bookmarked | Volume — dozens of files that all need the same kind of bookmarks applied. |

If your PDF has no bookmarks at all, start with the . If it already has bookmarks and something about them is wrong, the is almost always the right next stop — everything else in this cluster builds on a bookmark tree that's already correct.
