Why Use PDFWhisker to Watermark PDFs?
Adding a watermark to a PDF helps protect your content and communicate the document's status. Mark documents as 'CONFIDENTIAL', 'DRAFT', 'SAMPLE', or stamp them with your company name or copyright notice. PDFWhisker lets you customize the watermark text, opacity (transparency level), angle (diagonal, horizontal, or vertical), and font size to get exactly the look you need. The watermark is applied to every page of the document in a single operation. This is essential for protecting intellectual property, marking review copies, or branding documents before distribution.
Frequently Asked Questions

Is the watermark applied to all pages?

Can the watermark be removed after it's applied?
Watermarks applied by PDFWhisker are embedded into the PDF content. While they can potentially be removed with advanced PDF editing software, they serve as a strong visual deterrent against unauthorized use.
