Add or Remove Bookmark Numbers

Overview

Add/Remove Leading Numbers lets you add structured hierarchical numbering to bookmark titles or strip existing numbering patterns in a single operation. The dialog operates in one of two modes: Add Numbering or Remove Numbering.

How to use

  1. Open a PDF that contains bookmarks.
  2. Go to Plug-Ins > Bookmarks > Add/Remove Leading Numbers.
  3. Select Add Numbering or Remove Numbering.
  4. Configure the options for the chosen mode.
  5. Click OK to apply the changes.

Add Numbering mode

Adds hierarchical numbering prefixes to bookmark titles within a specified level range.

OptionDescription
Numbering style Choose from the following styles:
  • Digits (1.1.1) — Arabic numerals
  • Lowercase Roman (i, ii, iii)
  • Uppercase Roman (I, II, III)
  • Lowercase Letters (a, b, c)
  • Uppercase Letters (A, B, C)
Start level The first bookmark level to number (1–10).
End level The last bookmark level to number (1–10). Must be greater than or equal to the start level.
Include parent numbers When checked, builds hierarchical numbers that include the parent level (e.g. 2.3.1 instead of just 1).
Skip top level without children When checked, does not number top-level bookmarks that have no children.
Skip bookmarks with no children When checked, only numbers bookmarks that have child bookmarks beneath them.

Remove Numbering mode

Strips existing leading numbering from bookmark titles. Select one or more numbering styles to remove. You must select at least one style.

OptionWhat it removesExamples
Digits Arabic digit prefixes 1., 1.2., 3

Warning

Changes are applied immediately and cannot be undone from this dialog. Save your PDF before adding or removing numbering.

Tip

To re-number bookmarks that already have mixed numbering styles, first use Remove Numbering to strip all existing prefixes, then use Add Numbering with your preferred style.

Note

Level values are 1-based in the dialog and are validated to a range of 1 to 10. If the start level exceeds the end level, the dialog will show an error.
