About this tool

Load the bookmark outline from any PDF, edit the navigation tree — add, remove, rename, or reorganize bookmarks at any nesting depth — then save the result as a new PDF. Useful for fixing broken outlines, adding navigation to scanned documents, or reorganizing large reports.

Key features

  • Load existing outline

    Reads the full bookmark tree from your PDF so you can see and edit what is already there.

  • Nested bookmarks

    Add child bookmarks at any depth to create a rich hierarchical navigation tree.

  • Rename & reorder

    Edit titles and target page indices, then reorder by adding and deleting nodes.

  • Secure processing

    Files are processed in memory and never stored on our servers.

Frequently asked questions

What if my PDF has no bookmarks?
The editor will start empty. You can add any number of bookmarks from scratch and save them into the PDF.
Will the existing PDF content be changed?
No. Only the bookmark outline (navigation panel) is modified. Text, images, and page layout are untouched.
How do I create nested bookmarks?
Hover over any bookmark row and click the + icon on the right to add a child. You can nest to any depth.
What does page index mean?
Pages are numbered from 0. Page index 0 is the first page, 1 is the second, and so on. When a reader clicks the bookmark, the viewer will jump to that page.
