Transparency is adjustable, so your content stays legible behind the mark.

Your wording, your colour

Any text and any colour — not just a fixed set of stamps.

Private by design

Confidential documents never leave your device.

Frequently asked questions

Does this stop people copying my PDF?

No. A watermark discourages reuse and signals status, but it isn't encryption or access control.

Can I use an image or logo?

This tool adds text watermarks. For a logo, place it as text-free artwork using our PDF Editor.

Can the watermark be removed?

It's drawn into the page content, so it can't be toggled off in a normal reader — keep your unmarked original.

Does it work on scanned PDFs?

Yes. The watermark is drawn on top of the page whether it contains text or a scanned image.
