How do I add a watermark to a PDF?

Upload the document, type your watermark text, adjust style settings such as angle and opacity, and generate the marked-up PDF.

Does the watermark repeat on all pages?

Yes. The stamp repeats on every page at identical placement.

You control opacity so page content stays readable beneath the semi-transparent stamp.

No. Files are processed entirely inside your browser using client-side JavaScript. Your document is never uploaded to a server.
