Frequently Asked Questions
Can I create nested bookmarks?
Yes. You can create parent and child bookmarks for a hierarchical table of contents structure.
Will bookmarks work as clickable links in all PDF readers?
No. The bookmark data is stored in the PDF's metadata rather than as standard PDF bookmarks, so it is not rendered as a clickable outline in readers.
Can I edit bookmarks after adding them?
Yes. You can modify, reorder, or delete bookmarks before downloading the final PDF.
