How to Add Bookmarks to a PDF
Upload PDF
Drop the PDF you want to make navigable onto the page.
Define Bookmark Titles and Page Destinations
For each bookmark, type a title and the page number it should jump to.
Build Hierarchy
Add as many bookmarks as you need, in reading order.
Download PDF with Bookmarks
Click the button and download the file — the outline appears in the reader sidebar.
Improve Navigation in Long Documents
A 100-page manual without an outline is hard to navigate. Bookmarks let readers jump straight to the chapter they need.
The outline also helps search engines and assistive tools understand the document structure, which makes long PDFs more usable everywhere.

Frequently asked questions
What are PDF bookmarks?
Bookmarks form the document outline — the clickable table of contents shown in the sidebar of most PDF readers.
How many bookmarks can I add?
As many as you need. Each one pairs a title with the page it should jump to.
Do bookmarks change the pages?
No. Only the outline is added; the pages themselves stay exactly as they are.
