Advanced PDF Watermark Tool
Secure your documents with Porexo's advanced PDF Watermark Creator. Unlike basic tools, we offer a professional "software-like" experience directly in your browser. Whether you need to stamp "CONFIDENTIAL" on a contract or add your company logo to a presentation, our tool handles it with precision.
Drag & Drop Positioning
Simply click and drag your watermark on the preview canvas to place it exactly where you want.
Logo Support
Upload your brand logo (PNG/JPG) and adjust its transparency to create professional branded documents.
Client-Side Security
Your PDF file is processed entirely within your browser using WebAssembly. It is never uploaded to any server.
How to use the Mouse Adjust Feature?
We've made positioning incredibly intuitive. Once your PDF is loaded:
- Choose between Text or Image mode from the left panel.
- Move your mouse over the document preview.
- Click and Hold the watermark.
- Drag it to your desired location. The coordinates update automatically!
