Add Watermark

Overlay a text watermark across every page of a PDF, with control over opacity, rotation, and size.

About this tool

Overlays a diagonal (or any angle) text watermark across every page of a PDF - the same visual pattern used for "DRAFT" or "CONFIDENTIAL" stamps, without needing design software.

How to use it

1. Upload a PDF - the first page renders as a live preview showing roughly how the watermark will look.
2. Type the watermark text, then adjust opacity, rotation angle, and font size until it looks right.
3. Click Add Watermark, review the summary, then confirm to download the result.

FAQ

Can I use a logo or image as the watermark instead of text?

Not currently - this tool only supports text watermarks. It's applied as real text (not an image), so the output file stays small.

Will the watermark cover up my existing content?

It's drawn on top of the page, so a low opacity (the default is 30%) keeps existing text and images readable underneath.

Is the watermark applied to every page the same way?

Yes - the same text, size, opacity, and rotation is centered on every page of the document.
