How to add a watermark to a PDF
Upload your PDF, type the watermark text, adjust opacity/angle/size until it looks right, then download. The watermark is stamped once per page, centered.
Is my PDF uploaded anywhere?
No — the watermark is stamped entirely in your browser. Your PDF stays with you — your eyes only, we never get a look.
Can I control how visible the watermark is?
Yes — adjust opacity, size, and rotation angle until it looks the way you want before downloading.
Does the watermark apply to every page?
Yes — the same watermark text is stamped once, centered, on every page of the PDF.
