About PDF Bookmarks
Browse the outline of any PDF, add or rename bookmarks, build a nested table of contents, and save it back — all processed locally in your browser.
Give a long document a navigable spine
A long PDF without bookmarks is hard to move around in. Readers are left scrolling through dozens or hundreds of pages hunting for the section they need, and the document feels far less finished than one with a proper clickable outline in the sidebar. Bookmarks are that outline — the table of contents built into the file — and this tool lets you view, edit and create them so any report, manual, e-book or contract can be navigated with a single click instead of a long scroll.
You can add a bookmark that points to any page, rename entries so they read clearly, and nest them into a hierarchy that mirrors the document's real structure: parts, chapters, sections. The result is a PDF that opens with a usable map of itself, which makes it noticeably more professional to hand to a colleague, a client or a reader.
Editing an existing outline, or building one from scratch
Sometimes a document already has bookmarks that need tidying — a merged file might carry two overlapping outlines, or an exported report might have entries with unhelpful names. In those cases you're editing and reorganising what's there. Other times a PDF has no outline at all, often because it was scanned or produced by software that didn't generate one, and you're building a table of contents from the ground up. This tool handles both, showing the current outline and letting you reshape it or start fresh.
Adding an outline is purely additive: it changes how readers navigate the file, not the pages themselves, so text stays selectable and nothing is re-rendered or re-compressed. As with every tool here, the work happens in your browser with no account and no watermark, so building a table of contents for a confidential manual or internal report never sends the document to a server. Your original file is left untouched, so you can refine the outline, preview how it reads in the sidebar, and save again as many times as it takes to get the structure right.
Questions
Everything runs in your browser. How we keep files private
What are PDF bookmarks?
Bookmarks are the clickable outline — the table of contents — that appears in the sidebar of a PDF reader. Each one links to a page, letting readers jump directly to a chapter or section instead of scrolling through the whole document.
Can I build a nested table of contents?
Yes. You can nest bookmarks under one another to create a hierarchy — parts containing chapters containing sections — which is exactly how a long report or manual is usually organised.
Will adding bookmarks change the pages themselves?
No. Bookmarks are navigation that sits alongside the content; adding or editing them leaves the pages, text and images untouched.
Is my document processed privately?
Yes. The outline is read and written entirely in your browser, so your file is never uploaded.
