What Underline PDF actually does

Underline content on PDF pages in the visual editor. Use it for review markup where the original page should remain visible underneath.

Common situations

  • Making one focused visual change without rebuilding the document
  • Preparing a branded, marked-up or review-ready copy
  • Changing selected pages while keeping the rest of the PDF intact

A practical workflow

Before you rely on the result

New marks and overlays must fit the existing page geometry. Check placement on mixed-size or rotated pages before distributing the edited PDF.
