Understanding Add Watermark
A watermark is simply a semi-transparent text layer drawn on top of the existing PDF page content using the PDF drawing operators.
Why Add Watermark Matters
Prevents unauthorized use and clearly indicates the status of a document (e.g., "Do Not Copy").
Limitations of Add Watermark
While this tool is useful, keep in mind:
