A little guidance. A better result.
How to use Add PDF Watermark
Style the watermark — color, opacity, font, rotation — place it with presets or drag it, previewed live.
Prepare your input
Open the PDF and enter your watermark text.
Use the workspace
Choose colour, opacity, rotation and position; inspect the live preview.
Check your result
Export and check that the watermark does not obscure important content.
Know the limits
A watermark labels a document; it does not prevent copying or prove ownership.
