Question details

Users need a way to prevent unwanted bookmarks from appearing in exported PDFs when a Word document contains visible tracked changes and non-standard paragraph outline levels.

How to Prevent Ghost Bookmarks When Exporting Word Documents to PDF
Product
Microsoft Word
Device & OS
not provided
Scenario
Exporting a Microsoft Word document containing visible tracked changes to a PDF file.
Observed behavior
Word automatically generates unintended ghost bookmarks for paragraphs that use an outline level other than Body Text.
Before you start

Check your document's paragraph settings to ensure that standard text is not accidentally assigned a heading outline level, as this triggers unwanted bookmarks during PDF conversion.

Solution 1Recommended

Adjust Paragraph Outline Levels and PDF Export Settings

Correcting the paragraph outline level and explicitly instructing Word to only use true headings for bookmarks can prevent the ghost bookmarks issue.

This issue typically occurs when a paragraph has an outline level other than 'Body Text' but isn't styled as a standard heading. Word misinterprets these levels during the PDF export when tracked changes are visible.

1
Modify paragraph settings

Select the affected paragraph in your document. Right-click the selection and choose 'Paragraph' to open the paragraph settings dialog box.

2
Set outline level to Body Text

In the 'Indents and Spacing' tab, locate the 'Outline level' dropdown menu and change it to 'Body Text'. Click 'OK' to apply the changes.

3
Configure PDF export options

Go to File > Save As, choose PDF as the file format, and click on 'Options'. Under the bookmarks section, check the box for 'Create bookmarks using' and select 'Headings'.

4
Export the document

Click 'OK' and then 'Save' to export your document. This process preserves your visible tracked changes without generating ghost bookmarks.

Frequently Asked Questions

Why do tracked changes create unwanted bookmarks in PDFs?

When tracked changes are visible, Microsoft Word sometimes interprets paragraphs with non-standard outline levels as structural headings, automatically generating unwanted bookmarks during the PDF export process.

Can I keep tracked changes visible without them becoming bookmarks?

Yes. Ensure that all non-heading paragraphs have their outline level strictly set to 'Body Text' in the Paragraph settings, and choose 'Headings only' in the PDF export options before saving.

What if modifying the outline level ruins my document's layout?

If changing the outline level negatively impacts your document's structure or table of contents, export the document as-is to PDF and use a PDF editor tool to manually delete the ghost bookmarks afterward.
