Frequently asked questions
- What are PDF bookmarks?
- Bookmarks — also called the outline or table of contents — appear in a side panel in most PDF readers. Each one is a named link to a page, so readers can jump around a long document quickly.
- Can I edit existing bookmarks?
- Yes. Any bookmarks already in the PDF are loaded so you can rename them, change their target page, or remove them, then save.
- Does my file get uploaded?
- No. The outline is written into the PDF entirely in your browser — your document never leaves your device.
Give a long PDF a table of contents
A report, ebook, or manual is much easier to navigate when readers can open the bookmarks panel and jump to any section. Edit Bookmarks lets you build that outline: add a bookmark for each chapter or section, give it a title, and point it at the right page. Existing bookmarks load in so you can tidy them up.
Simple, in your browser
Name each bookmark and set its page number — that's it. When you save, HivePDF writes a proper PDF outline that works in Acrobat, Preview, browsers, and other readers. It all happens locally, so even a confidential document stays on your device.
Notes and limits
This editor writes a flat list of bookmarks (no nested sub-levels yet), which covers most tables of contents. Bookmarks jump to the top of the target page. To reorder the actual pages instead of the outline, use Organize.
How the outline is stored
A PDF's bookmarks live in a separate outline structure inside the file, distinct from the page content itself — each entry is just a title string and a destination, typically a page number and zoom level. That's why adding or renaming bookmarks doesn't touch the pages at all: Edit Bookmarks reads that structure if it exists, lets you edit the list, and writes it back when you save, leaving the document's actual content untouched.
Planning an outline before you build it
For anything longer than a few pages, it helps to skim the document first and jot down where each chapter, section, or appendix starts, then add bookmarks in that order so the outline reads top to bottom in the panel. Match bookmark titles to the headings printed on the page so readers aren't guessing which entry to click.
Pairing with other tools
If you're also numbering the pages, run Add Page Numbers so the printed numbers match what readers see in the outline panel. If pages need reordering first, do that in Organize before setting bookmark targets, since page numbers shift once pages move.
