About This Tool
Free PDF watermark tool online — add custom text watermarks to every page of a PDF document. Control the watermark text, font size, color, opacity, rotation angle, and position (diagonal, centered, or corner). No server uploads, no account, entirely browser-based. Businesses use PDF watermarks to mark documents as "CONFIDENTIAL", "DRAFT", or "FOR REVIEW ONLY" before sharing with external parties. Freelancers watermark proposal PDFs with "SAMPLE" until payment is received. Legal and HR departments add "DO NOT DISTRIBUTE" to sensitive documents. The watermark is burned into the PDF pages on download.
