Label documents before they travel

Type the watermark text, set its size and opacity, choose diagonal or horizontal placement, and every page gets stamped consistently. The watermark is drawn into the page content, so it survives printing and re-saving.

Everything happens locally in your browser — your documents are never uploaded to a server, so contracts, invoices and ID scans stay on your device.

Frequently asked questions

Can the watermark be removed later?
It becomes part of the page content — not a separate layer a viewer can toggle off. Like any watermark, a determined editor could cover it, but casual removal isn't possible.
Can I watermark only some pages?
The stamp is applied to all pages for consistency. To watermark a subset, split those pages out first, watermark them, and merge back — all three tools are on this site.
