About PDF Bookmark Editor

PDF Bookmark Editor is a browser-based tool for adding and editing PDF bookmarks, including chapter, section, and subsection levels. It loads existing bookmarks, imports or exports them as a text file, and merges PDFs while retaining bookmarks. It also supports rotating, deleting, selecting, and reordering pages, plus multi-term search.

The app runs locally and can be installed for offline use. It does not set vertical position within a page, cropping is not practical in the app, and annotation or compression require separate tools such as Firefox/Librewolf or Ghostscript commands.

PDF Bookmark Editor FAQ

Can it jump to an exact location within a page?
No. It modifies bookmarks for pages but does not do vertical position within PDFs.
Can it annotate a PDF?
No. For annotation, adding text, highlighting, or adding a signature, the source directs users to open the PDF in Firefox or Librewolf.
How does compression work?
It copies a Ghostscript command to run in a terminal in the same directory as the PDF, rather than compressing inside the app.
Is something wrong or out of date?
