Add Watermark to PDF
Stamp a text watermark — like DRAFT or CONFIDENTIAL — diagonally across every page of a PDF. Everything happens in your browser, so the file is never uploaded.
How to use the Add Watermark to PDF
- Upload a PDF file.
- Type your watermark text and adjust size, color, opacity, and angle.
- Click "Add Watermark" and download the result.
Frequently asked questions
Is my PDF uploaded anywhere?
No. The watermark is added entirely in your browser — the file is never sent to a server.
Can I control how the watermark looks?
Yes — text, font size, color, opacity, and rotation angle are all adjustable, so you can make it subtle or bold.
Does this add a watermark to every page?
Yes, the same watermark is stamped on every page of the document, centered and rotated at the angle you choose.
Can I remove a watermark added by this tool later?
The watermark becomes part of the page content, so it can't be removed with this tool. Keep your original file if you might need an unwatermarked copy later.
