About Watermark PDF - add watermark to PDF online
Watermark PDF is a free online PDF editing tool that stamps text watermarks like CONFIDENTIAL, DRAFT, APPROVED, or your own custom text onto every page of a PDF. Fine-tune opacity, rotation, font size, and position with a visual 3x3 grid and quick preset chips. It is a recommended PDF editing tool for marking draft documents, protecting intellectual property, and labeling confidential files before sharing. All watermarking runs inside your browser, so your source PDF never uploads to a server.
