About PDF watermarks
Adding a watermark to a PDF is common for marking documents as confidential, draft, or for branding. This tool adds a text watermark to every page of your PDF using the pdf-lib library — processing happens entirely in your browser and your files never leave your device. You can customize the watermark text, size, color, opacity, and position to match your needs.
