Watermark PDF
Stamp “Confidential”, “Draft” or your name over every page.
Apply a text watermark over every page of a PDF — such as “CONFIDENTIAL”, “DRAFT”, “COPY” or your company name. Choose the text, opacity, size, color and angle (diagonal or horizontal). Perfect for protecting documents, marking versions or identifying copies. Processed in your browser, no upload.
Frequently asked questions
Can the watermark be removed later?
The mark is drawn over the content as part of the page. Someone with advanced editing tools could try to remove it; it is a visual deterrent, not cryptographic protection. For real security, combine it with access restrictions.
Can I make it subtler or stronger?
Yes. Adjust the opacity (from a very subtle 12% to a bold 50%), the size and the color. A diagonal mark at 20% is usually readable without disturbing the document.
Does it work with any PDF?
Yes, as long as it is not password-protected — in that case, unlock it first. The tool preserves the original content and just adds the text on top, without recompressing.
