Marca de agua

Añade marcas de agua de texto o imagen a tus PDFs

pdfty's watermark tool adds a text watermark — like CONFIDENTIAL, DRAFT, your name, or a date — to every page of a PDF. Adjust opacity, font size, and position. The result is one PDF with the watermark baked in.

Useful for sharing draft documents that should not be circulated as final, for marking proofs, or for branding internal copies. Diagonal watermarks are common for visibility while staying out of the way of the main text.

Built with PyMuPDF for precise positioning. Works on any number of pages. Pages keep their original size and quality.
