- Click “Add watermark” — every page is stamped and the finished PDF downloads instantly.
Features
Five placement styles cover every convention: the classic diagonal stamp, centered, top, bottom, and a tilted header style. Text auto-shrinks to fit narrow pages, opacity is freely adjustable from a subtle ghost to a bold mark, and any color can be chosen — the stamp applies uniformly across all pages in one pass.
Benefits & Use Cases
Mark contracts “DRAFT” before circulation so nobody mistakes them for final. Brand client deliverables with your company name. Stamp “CONFIDENTIAL” on sensitive reports. Photographers protect proofs; HR marks sample documents — a visible deterrent against misuse that takes seconds to apply.
Tips
Keep opacity low (15–30%) for the classic watermark look that does not obscure content. Diagonal placement is hardest to crop out. Short, uppercase words read best at an angle. Remember a text watermark deters casual copying but is not copy protection — for real document security, combine with proper access controls.
