Stamp CONFIDENTIAL or DRAFT across a PDF

Mark a document as confidential or draft, privately.

Files never leave your device · No upload · Free

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.

How to add a confidential watermark to a PDF

  1. 1

    Add your PDF

    Drop in the document you want to mark.

  2. 2

    Type the label

  3. 3

    Apply and download

    Save the stamped PDF, produced on your device.

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.
