This tool adds a text watermark (like "CONFIDENTIAL" or "SAMPLE") or a logo image to every page of a PDF at once. Because the watermark is drawn directly onto the existing page content rather than rendering the page as an image, the original text, vectors, and quality of your PDF stay completely intact — the watermark is simply layered on top. A live preview updates automatically as you adjust position, rotation, opacity, and size. All processing happens locally in your browser; your file is never uploaded to a server.
