How to Add Watermark to a PDF Online for Free

Why Watermark a PDF?

A watermark on a PDF serves multiple purposes — it identifies the document owner, deters unauthorized copying, marks draft versions, or classifies documents as confidential. Unlike image watermarks, PDF watermarks are applied to every page simultaneously and are embedded into the document structure.
