How to watermark a PDF with text

A watermark marks a draft, a sample, or a confidential copy. The words are drawn on every page and saved into the PDF. They are not a separate layer you can switch off later.

Add your PDF.
Type a short label, up to 40 characters.
Set how faint the text should be, then download.

For a signature on one page instead of a stamp on all pages, use Sign PDF.

FAQ

Are files uploaded?

No. The stamp is drawn locally.

Can I use a logo image?

This tool stamps text. An image logo needs to be placed as part of a page in another app.

Can I watermark one page only?

Split that page out, watermark it, then merge it back with the rest.

Will the watermark print?

Yes. It is part of the page content.
