Add text like "CONFIDENTIAL" or "DRAFT" across every page.
Protect and brand your documents by stamping text like CONFIDENTIAL, DRAFT or your company name across every page. This Watermark PDF tool gives you control over the text, size, color, angle and opacity — and it works entirely in your browser, so your file is never uploaded.
Will the watermark appear on every page?
Yes — your text is stamped across all pages of the PDF.
Can I make the watermark faint?
Yes — lower the opacity slider for a light background effect.
Do you store my document?
No — nothing is uploaded; the watermark is added locally.
