Watermark a PDF.

Type a word like CONFIDENTIAL, or drop in your logo, and it stamps onto every page. A live preview shows exactly where it lands, so you can nudge the position, dial the opacity down, and set the 45-degree diagonal before you apply. Sit it above the page content, or tuck it behind the text.
