How do I add bookmarks to a PDF?

Write one line per bookmark, such as 1 Introduction or 12 Results, and download the PDF. You can paste a table of contents straight in and then adjust the page numbers.

What happens to the bookmarks that were already there?

They are replaced by exactly the list in the box. Because the box starts with the current bookmarks, editing it keeps what you want and removes only what you delete.

Can I create nested bookmarks?

Not yet — every bookmark is written at the top level. For long documents, a flat list with clear titles and page numbers is still a fast way to navigate.

Before you start

The thumbnail beside each bookmark shows the page it opens — check it's the right one.
Use the indent button to put a bookmark under the one above, so chapters get their sections.
Prefer a list? Edit as text takes one bookmark per line: the page, then the title.
