PDF Watermark Tool

This tool applies a visible watermark to PDF documents by overlaying a watermark layer on each page. It supports text-based watermarks or image-based marks, with adjustable position, opacity, and size. The user uploads a PDF, selects watermark style, and the system generates a new PDF in which every page contains the watermark. Conceptually, the watermark is a non-destructive overlay that does not modify existing content, only adds a repeated visual layer. Beneficiaries include authors who want to indicate drafts, publishers protecting proprietary materials, educators sharing course packets, and sales teams distributing brochures. Unique value comes from a server-side, no-install workflow that preserves document integrity while providing batch-ready processing and predictable output formatting. Core features include per-page control (apply to all pages or a range), opacity and scale tuning, and a simple output format that remains fully compliant with PDF readers. Typical use cases cover pre-distribution proofs, report sharing, and marketing collateral that must carry ownership marks.
