About Edit PDF Bookmarks

Edit PDF bookmarks to turn a 200-page manual, a thesis or a merged stack of scans into something people can find their way around. Existing bookmarks load into a list next to a page preview. Add bookmark here creates one for the page you're looking at and suggests a title from its largest text. Rename it, change its page number, move it up or down, or use » and « to nest it under another.

Find headings reads the document, picks out lines set in larger type and proposes up to three levels of bookmarks in one go. You can then tidy the list by hand. The saved PDF is set to open with the bookmarks panel showing in readers that support it. If someone only needs one chapter, Split PDF can cut it out by its page range.

FAQ

Edit PDF Bookmarks: questions and answers

How do I add bookmarks to a PDF?
Open the PDF, go to the page and click Add bookmark here, or press Find headings to create them from the document's headings. Then click Save bookmarks. When you're combining several files anyway, Merge PDF can add a bookmark for each one as it merges them.
Can I edit PDF bookmarks that are already in the file?
Yes. They're loaded into the list when you open the PDF. Rename, move, re-nest or delete them, then save.
Why did Find headings miss some chapters?
It looks for lines set in larger type than the body text. Headings the same size as the body, or on scanned pages without real text, can't be detected, so add those with Add bookmark here.
Is it free to edit PDF bookmarks?
Yes. Visitors get 2 tasks in total and free accounts 2 a day, for files up to 50 MB, and VIP has no daily limit with files up to 1 GB.
Is my manual or thesis stored after saving?
No. The PDF and the bookmarked copy are erased from our server an hour after the task, and nobody opens them in between.
