PDF Structure & Navigation Tools
11 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. | Open |
Bookmark Editor | PDF with existing bookmarks | The same PDF, bookmarks fixed | Bookmarks that already exist but are wrong, misnamed, or badly nested. | Open |
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. | Open |
Merge with Bookmarks | Several PDFs, in the order you want them | One PDF, every source outline carried across, optional contents page | Combining documents without losing the bookmarks a plain page-copy merge drops. | Open |
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. | Open |
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. | Open |
Search PDF Text | One or many PDFs with a text layer | Every hit with page and context; CSV, Markdown or grep-style export | Locating something across a stack of documents without opening each one. | Open |
Markdown to PDF | Markdown text or a .md file | PDF with nested bookmarks, optional contents page, clickable links | READMEs, specs and notes that should ship as a navigable PDF, not a scroll. | Open |
Password Protect PDF | Any PDF (already-protected ones too, with their password) | The same PDF, encrypted — bookmarks, links and metadata kept | Sending a document that should need a password to open, or that should not be copied or edited. | Open |
Unlock PDF | An encrypted PDF, plus its password if it needs one to open | The same PDF with no encryption | Files that ask for a password every time, or refuse to print or copy — when you know the password. | Open |
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. | Open |
Not sure where to start?
If your PDF has no bookmarks at all, start with the TOC generator. If it already has bookmarks and something about them is wrong, the bookmark editor is almost always the right next stop — everything else in this cluster builds on a bookmark tree that's already correct.
