Will my bookmarks survive merging or reordering pages?

No — tools that rebuild the page list (Merge, Reorder, Delete Pages) drop the outline. Do your page surgery first and add bookmarks as the final step of the workflow.

Can I delete all bookmarks from a PDF?

Yes. Remove every entry and save — the outline is removed from the document entirely, and the reader sidebar comes up empty.

Where on the page does a bookmark land?

Bookmarks saved by this tool jump to the top of the target page at fit-to-page zoom. PDF bookmarks point at pages, not at text strings — precise mid-page targets aren't part of how outlines work here.

Can I create nested bookmarks?

Existing nesting is read, displayed indented, and preserved exactly when you save. New bookmarks you add are created at the top level — the editor doesn't currently offer an indent control for new entries.

Why does an imported bookmark show page 1 when it pointed elsewhere?

Some PDFs use named destinations that can't be resolved to a page number. The tool preserves such destinations through a save as long as you don't edit that entry's page — but it can only display them as page 1 in the list.

About Edit PDF Bookmarks

Bookmarks — the clickable outline in a PDF reader's sidebar — are what make a 200-page document navigable in three clicks. Professionally published PDFs usually have them; scans, merges, and word-processor exports usually don't. Convertora's bookmarks tool reads whatever outline a PDF has and lets you edit it: rename entries, repoint them at different pages, delete dead ones, and add new ones.

The reader is more thorough than most: it walks nested outline trees, follows GoTo actions, and resolves named destinations, so bookmarks load correctly even from PDFs that store their outline in roundabout ways. Nesting is preserved — child entries display indented under their parents, and the hierarchy is written back intact when you save.

Editing happens in a straightforward list: each bookmark is a title plus a page number, with a remove button, and an Add Bookmark button appends new entries. When you save, the entire outline is rebuilt cleanly into the file.

How to use it

1Upload your PDF (up to 100 MB). Existing bookmarks load automatically, with nested entries shown indented.
2Edit any entry's title or target page number. Page numbers are the familiar 1-based kind.
3Remove entries that no longer apply, or click Add Bookmark to create new ones — new entries are added at the top level.
4Click Save Bookmarks. The outline tree is rebuilt with the original hierarchy preserved and written into the file.
5Download the result, saved with a -bookmarked suffix.

Common use cases

Adding chapter navigation to a merged bundle, since merging doesn't carry bookmarks over.
Fixing an outline whose entries point at the wrong pages after pages were added or removed upstream.
Renaming auto-generated bookmark titles ('Section 1.2.3') into something humans actually scan for.
Stripping a stale outline entirely from a heavily reworked document.

Tips

A useful minimum outline: one bookmark per section heading plus one for any appendix. Ten entries transform a long document; you don't need fifty.
Note your target page numbers before you start — the editor shows the list, not page previews, so having 'Chapter 3 = page 41' jotted down speeds things up.

100% private — runs in your browser

Convertora processes everything on your device using JavaScript and WebAssembly. Files never leave your browser, are never uploaded to a server, and are never seen by us or anyone else. The moment you close the tab, the data is gone — there is no temporary cloud copy, no log entry, no retained backup.

Because the work happens locally, processing speed depends on your device — but there are no rate limits, no daily caps, and no file size restrictions beyond what your browser can handle in memory. No signup, no account, no payment. The tool works the same in incognito mode, on a corporate network, or after the page has loaded once, even with the network disconnected.
