# Edit PDF bookmarks & outline — rename titles, no upload

> View a PDF's bookmark outline and rename its titles in your browser, then save a new file. Runs locally with pdf-lib — nothing uploaded.

View the bookmark outline of a PDF and rename its titles in place, then save a new file. The outline is read and rewritten on your device, so the PDF isn't uploaded.

A PDF's bookmarks are the outline readers use to jump around a long document, and they're often mislabeled after merges or exports. This tool lets you clean up those titles so the navigation makes sense, without any other change to the file.

It's focused on renaming — structure and destinations stay as they are. To rearrange the actual pages behind the outline, use Organize.

## How to

1. **Open the PDF.** Drop a PDF that has an outline/bookmarks.
2. **Rename titles.** Edit the bookmark titles in the tree in place.
3. **Save.** Download the PDF with your updated titles.

## FAQ

### Can I add or remove bookmarks?

This tool renames existing outline entries. It doesn't add, delete, reorder, or change bookmark destinations — those are out of scope.

### What if my PDF has no bookmarks?

There will be nothing to edit — bookmarks come from the file's outline tree, which not every PDF includes.

### Is my document uploaded?

No. The outline is loaded and saved with pdf-lib in a worker on your device, so the file stays local.
