Add Text Watermark to PDF - Online PDF Watermarker

Easily apply a text watermark (such as "Confidential", "Draft", "Sample", your company name, or a copyright notice) diagonally to all pages of your PDF document using our free online tool. You can fully customize the watermark text, adjust its font size for optimal visibility, and set the opacity to make it as subtle or prominent as you need. This is an excellent way to protect your documents, indicate their status (e.g., "DRAFT"), or subtly brand your PDFs before sharing or distribution. For image-based watermarks, see our Image Watermark tool.
