About PDF Watermark

PDF Watermark stamps text across every page — a company name, a status like DRAFT, or a recipient's email — with adjustable size, opacity and angle.

It is a lightweight way to mark confidential documents or deter casual sharing without flattening the file.

1
Upload the PDF
Choose the document and preview the first page.
2
Write the watermark
Set the text, size, colour, opacity and rotation. A diagonal, low-opacity mark is the usual choice.
3
Apply and download
The mark is written onto every page; the original text stays selectable.

Can the watermark be removed?

It is drawn into the page content, so removing it requires editing the PDF. It is a deterrent, not DRM.

Can I use an image watermark?

This tool handles text watermarks; an image logo is not supported.

Will it cover the text?

At low opacity it sits behind the content. Increase opacity if you need a stronger mark.

Can I watermark only some pages?

Currently the mark is applied to all pages.
