About This Feature

Overview

WPS PDF underline is used to add emphasis formatting to selected text during PDF text editing, and it can also be used again to remove the underline. It is useful for marking key content in contracts, reviewed drafts, study materials, and internal revision files.

Core capabilities include:

  • Add an underline from the ribbon for routine formatting tasks.
  • Add an underline from the floating toolbar for quick inline edits.
  • Toggle underline with a keyboard shortcut for faster text formatting.

In PDF editing scenarios, you need to enter text editing mode before applying underline formatting to editable text. If the file is a scanned PDF or image-based content, OCR or editable text recognition may be needed first.
