Type CONFIDENTIAL, DRAFT, a company name, or a date. The same string is centered on each page. The stamp is drawn directly on the PDF — the result stays a real document, not a screenshot.
Font sizes 24 to 72 cover a small footer-style mark or a full diagonal stamp. Opacity 10–50% keeps the body readable. Default −45° is the classic diagonal; 0° and 45° are there when you need them. Gray, red, blue, or black.
Thumbnails show every page so you confirm you grabbed the right file before you stamp. You still download to see the watermark itself — the grid is the original pages, not a live overlay.
The watermark is drawn locally in this tab. Contracts marked CONFIDENTIAL are not uploaded to apply the stamp. No signup to download.

Pick 24/36/48/72, a fade level, −45° / 0° / 45°, and gray, red, blue, or black.
Click apply. The watermarked PDF downloads. Start over to try different wording.
