Understanding PDF Bookmarks
What are PDF Bookmarks?
PDF bookmarks (also called the PDF outline) are navigation links stored inside the PDF file that appear in the "Bookmarks" panel of PDF readers like Adobe Acrobat, Chrome, and Firefox. Each bookmark has a title and a destination - typically a page number. Bookmarks are arranged in a tree: top-level entries represent chapters, and nested children represent sub-sections. Our PDF bookmarks editor lets you view, add, rename, reorder, and delete bookmarks without any desktop software.
How Our PDF Bookmarks Editor Works
- 1Upload your PDF:Drop or select any PDF. The PDF bookmarks editor instantly reads the document's existing outline using pdfjs-dist and renders every bookmark as an editable row showing its title and destination page. PDFs with no existing bookmarks start with an empty editable list.
- 2Edit the bookmarks: Double-click any title to rename it. Change the destination page using the inline number field. Hover any row to reveal the rename, add child, and delete action buttons. Add new top-level bookmarks from the sidebar form. All changes update the live list instantly.
- 3Save & download:Click "Save & Download PDF". The tool loads your PDF into pdf-lib, writes the updated bookmark tree as a PDF outline, and triggers a browser download of the updated file. Your original PDF is never modified - you always get a new copy.
What You Can Edit with the PDF Bookmarks Editor
- Rename Bookmarks: Double-click any bookmark title to edit it inline. Changes apply immediately to the live outline.
- Change Destination Pages: Update the page number field on any bookmark row to redirect that bookmark to a different page in the document.
- Add New Bookmarks:Use the sidebar form to add new top-level bookmarks. Use the "+" button on any existing row to add a nested child bookmark beneath it.
- Delete Bookmarks: Click the trash icon on any row to remove that bookmark and all its children from the outline.
Privacy, Compatibility & Notes
The PDF bookmarks editor processes your file entirely in your browser - your PDF never leaves your device. The output PDF is fully compatible with Adobe Acrobat, Chrome PDF viewer, Firefox, and all major PDF readers. Note that some scanned image-only PDFs may not preserve bookmarks if they were not originally generated with outline support. For best results, use the PDF bookmarks editor on PDFs created from Word, InDesign, LaTeX, or other document authoring tools.

Frequently Asked Questions About PDF Bookmarks Editor
PDF bookmarks are navigation links stored inside a PDF file that appear in the Bookmarks or Outline panel of PDF readers. Each bookmark has a title and a destination page. Readers can click a bookmark to jump directly to that page. Bookmarks can be nested to create chapter and sub-section hierarchies.

Some PDF readers require you to open the Bookmarks or Outline panel manually - the panel is not always shown by default. In Adobe Acrobat, press F5 or go to View → Navigation Panels → Bookmarks. In Chrome, look for the bookmark icon in the PDF toolbar. If the panel is visible but empty, the PDF may not have supported bookmark embedding during generation.
The PDF bookmarks editor works on unencrypted PDFs. If your PDF requires a password to open, you will need to remove the password protection first using our PDF Unlock tool, then re-upload it here.
No. Bookmarks are stored as metadata in the PDF structure and are completely separate from the page content, text, images, and layout. Editing, adding, or deleting bookmarks has no effect whatsoever on the visual content or layout of your PDF pages.
