Complete guide to using PDF Bookmarks Editor — a free online tool by akousa.net.
Get started in seconds — no signup required
The PDF Bookmarks Editor lets you create, edit, reorder, indent, and delete bookmarks — also called the PDF outline or table of contents — in any PDF document. Bookmarks are hierarchical navigation anchors embedded in the PDF file that allow readers to jump directly to chapters, sections, and subsections. Professional PDFs without bookmarks force readers to scroll through hundreds of pages manually. This tool supports nested bookmark hierarchies and JSON import/export for batch management, with all processing done privately in your browser.
Works directly in your browser — no downloads needed

Upload a PDF to see its existing bookmark tree. Add new bookmarks by specifying a title and target page number, drag entries to reorder them, use indent/outdent to create nested hierarchies, and click the pencil icon to rename any bookmark. Import bookmarks from a JSON file for bulk operations, or export the current structure as JSON for reuse. Click Save PDF with Bookmarks to download the updated document.
PDF Bookmarks Editor is a free, browser-based tool that runs entirely on your device — no signup, no uploads, and no tracking. Built for speed and privacy, it gives you instant results without leaving the page.
