Frequently asked questions
Can watermarks be removed later?
Visible watermarks can sometimes be defeated. For strong redaction of secrets use Redact PDF, not a watermark.
Every page or selected pages?
Typical flow stamps all pages. Split first if only a subset should be marked.
Image watermark transparency?
Use a PNG with transparency for cleaner logos over content.
Print vs screen?
Check a printed page if physical copies matter — opacity that looks fine on screen can vanish on paper.
Confidential footer instead?
Header & Footer can add recurring text; Watermark is better for diagonal or repeated marks.
