Frequently Asked Questions
Is it free?
Yes. No signup required.
Is my file safe?
Yes — your PDF is processed entirely in your browser and never uploaded.
Will this keep my PDF's existing bookmarks?
Top-level bookmarks are read in and pre-filled as a starting point you can edit. Saving replaces the whole bookmark list with what's shown in the editor.
Can I create nested or sub-bookmarks?
Not yet — this editor works with a flat list. If your original PDF had nested bookmarks, they won't be preserved after saving.
What if a bookmark's target page can't be figured out?
It's pre-filled as page 1 so you can correct it — this can happen with a small number of PDFs that use named destinations instead of direct page links.
Can I reorder bookmarks?
Yes — use the up and down arrows next to each bookmark.
