About this tool

Give a long PDF the navigation it deserves by building or editing its bookmarks and assembling a clickable table of contents inside the file. You can add fresh bookmark entries, rename or reorder the ones already there, and aim each bookmark at the precise page it should open, which leaves your document with a tidy outline that shows up in the sidebar of any standard PDF reader for instant jumping. It is perfect for wiring chapter links into a lengthy report, helping readers glide through ebooks and manuals, or imposing structure on a scanned multi-section document. All of the editing takes place locally in your browser, so the file is never handed off to a server and your content stays private throughout. The bookmarked PDF preserves its original quality intact and is ready for download as soon as you finish arranging the outline. Authors publishing ebooks, professionals preparing lengthy reports, and educators organizing course material for easy navigation will get the most out of it.
