How to add a chapter list to a PDF

Bookmarks make a long PDF easier to navigate. They let the reader jump to a section without scrolling through every page. Create PDF Bookmarks adds a simple list of named destinations to your document.

1. Open your file

Choose the PDF and note the real page number where each section begins. Page 1 means the first physical page, including a cover if the file has one.

2. Choose whether the new list should replace the existing bookmarks or be kept alongside them.
