Bookmarks from Word
Bookmarks are a group of links pointing to their destinations – such as different page views, sections in the current document or to other documents. Selected word headings or styles can be converted to PDF bookmarks with a hierarchy of levels you decide, without disturbing the logical structure of the original Word document.
Bookmarks help readers to browse PDF documents easily, especially when reading a collection of documents.
Click the 
PDF Links button in the Nuance PDF toolbar or use the corresponding menu item. This opens the Nuance PDF Settings for Word dialog box, whose Bookmarks tab offers the following settings:
Generate Bookmarks, Links, Comments, Tags in resulting PDF file
Select this checkbox to have changed settings applied to future conversions.
Save Word File Before Conversion, if Possible
Save the Word file before conversion. If it is read-only, this option is ignored.
Bookmark – Paragraph Style – Level
All the Word headings and styles belonging to the current document are listed here. Choose the styles to be converted to bookmarks by selecting checkboxes in the Bookmark column.
Meaning of the checkbox:
Checked (selected): 
Unchecked (de-selected): 
Decide a bookmark level (indent) for each style. Bookmarks are organized into a navigation tree with different levels – like the heading structure in Word documents. Select a bookmark, then click on the level number to modify it. The default is 1.
In the lower selection box, you can specify how to display the target page view: retain the source page zoom rate, fit page, fit width, fit height, or fit visible.
Note
You can also choose to have bookmarks transferred from Microsoft Excel (one per sheet) and PowerPoint (one per slide).
