How to add bookmarks to a PDF
Bookmarks are the index that PDF readers show in a side panel: each entry takes you to a page with one click, and they can be nested by chapters and sections.
Choose the PDF. If it already has bookmarks, they appear in the list so you can edit them.
Add bookmarks with their title and page, or create them one per page or from the document's headings. Reorder and nest them with the arrows.
Click Save bookmarks and download the PDF: the content of the pages does not change.
