About the PDF Bookmarks / TOC Editor

PDF Bookmarks / TOC Editor imports the existing QPDF outline tree and resolves bookmark destinations to physical page numbers. Edit titles and destinations without changing page artwork.

Add chapter or section bookmarks, reorder them, indent or outdent hierarchy levels and choose whether groups are expanded by default. The resulting PDF opens its bookmark panel through the standard UseOutlines page mode.

The output outline tree writes complete Parent, Prev, Next, First, Last and Count relationships. It is then structurally validated and re-imported to compare every title, hierarchy level and destination page.
