Overview
Merge Duplicate Bookmark Titles consolidates consecutive sibling bookmarks that share the same title into a single bookmark. Children from the duplicate entries are moved under the surviving bookmark, producing a cleaner, de-duplicated outline.
How to use
- Open a PDF that contains bookmarks.
- Go to Plug-Ins > Bookmarks > Manage & Organize > Merge Duplicate Bookmark Titles.
- Select the level scope: All levels, a single level, or a level range.
- Click OK to merge duplicates within the chosen levels.
How it works
| Behaviour | Details |
|---|---|
| Consecutive matches only | Only adjacent siblings with identical titles are merged. Non-adjacent bookmarks that happen to share a title are left untouched. |
| Child consolidation | All children from the duplicate bookmarks are moved under the first (surviving) bookmark. The duplicates are then destroyed. |
| Open state preservation | If any duplicate bookmark is open (expanded) and the surviving bookmark is closed, the surviving bookmark is set to open so that no content is hidden. |
| Recursive processing | When the selected range spans multiple levels, duplicates are merged at each level from the top down. Children within merged groups are then scanned for duplicates at deeper levels. |
Scope options
| Option | Description |
|---|---|
| All levels | Scans every level of the bookmark tree for consecutive duplicates. |
| Single level | Merges duplicates only at the specified level number. |
| Level range | Merges duplicates within the specified start and end levels (inclusive). |
Warning
Merging is applied immediately and cannot be undone. Consider saving a backup of your PDF before running this operation.
Note
After merging, a message reports how many duplicate bookmarks were removed. If no consecutive duplicates are found, you will see “No duplicate bookmark titles were found.”
