About this tool

Edit PDF Bookmarks — Add, Rename and Reorder the Outline

Add bookmarks to a PDF, rename them, point them at the right page and arrange them in levels. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.

Build the Outline

Add a bookmark for the open page, rename it with a double-click and point it at another page whenever the document changes.

Levels and Order

Move bookmarks up or down, nest them under the one above or move them up a level — with buttons, Alt + arrow keys or by dragging.

Written Into the File

On download the bookmark tree is saved in the PDF, so every PDF reader shows it in its sidebar.

How to use it

  1. Drop the PDF. The editor opens with the Bookmarks tab in the left sidebar.
  2. Go to a page and click Add bookmark for this page.
  3. Double-click a bookmark to rename it; drag it to move it before, after or inside another.
  4. Use Point to the open page if a bookmark should open a different page.
  5. Download the edited PDF.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.

Can I edit the bookmarks a PDF already has?

Yes. Existing bookmarks are shown as a tree; rename, move or delete them like new ones.

Can I undo a change?

Yes. Each bookmark change is one undo step, and the list of changes can revert all bookmark edits at once.

Can I edit bookmarks on a phone?

Not yet. The bookmarks open in the editor's left sidebar, which appears on screens at least 1024 pixels wide, such as a computer or a tablet in landscape.

Is it really free?

Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
