Stamp CONFIDENTIAL or DRAFT across a PDF
Mark a document as confidential or draft, privately.
Laying CONFIDENTIAL or DRAFT across every page tells readers how to treat a document at a glance. This tool stamps that text over your pages in your browser, so a sensitive file is never uploaded to mark it.

Why mark confidential files locally
A document you need to mark CONFIDENTIAL is, by definition, sensitive. Stamping it in the browser means it is never uploaded to a watermarking service to do so.
