A mark across the page says what a document is before anyone reads a word of it — a draft, a copy, not for circulation. This puts one on every page, sized to fit whatever page it lands on.

What people use it for
- Mark a document DRAFT before sending it for review.
- Stamp CONFIDENTIAL on something being shared outside the team.
- Put a company or client name across pages of a proposal.
What goes in, and where it goes
- What it accepts
- One PDF at a time, plus up to 60 characters of standard Latin text. There's no size setting — the mark is scaled to fit each page, so mixed page sizes in one document all come out right.
- What you get back
- One PDF with the mark on every page, drawn over the existing content. Page count, order, sizes, rotation and the text underneath are unchanged.
- Where your file is processed
- Watermark PDF runs in your browser. The file and the text you type are used only in this tab, and neither is uploaded. Nothing is kept once you close the tab.
Common questions
Does a watermark stop someone copying the document?
No, and it isn't meant to. It's drawn onto the page like any other content, so a PDF editor can remove it. It tells a reader what they're looking at; it doesn't restrict what they can do. To require a password to open the file, use Protect PDF.
Can I watermark only some pages?
Not in this version. The mark goes on every page. If you only need part of a document stamped, split it first, watermark that part, then merge it back.
Why was my text rejected?
Almost always because it uses characters the built-in font can't write — emoji, or a non-Latin script. The font covers standard Latin, including accents like é and ñ. Rejecting is deliberate: silently dropping the characters it can't draw would be worse.
Will the mark be the right size on every page?
Yes. It's fitted to each page individually rather than set to a fixed size, so a document mixing A4 and letter, or portrait and landscape, gets a mark that fits each one. Pages that were scanned sideways are handled too — the text faces the reader rather than running up the edge.
