Frequently Asked Questions

How does in-browser PDF watermarking work securely?

All watermarking and text overlay calculations run right in your browser. Raw document files never leave your computer or get uploaded to any servers, ensuring complete document security and privacy.

Can I overlay watermarks in multiple tiled positions?

Yes, absolutely! Next to corner, header, and centered placements, our tool features a "Tiled" (Grid-tiled) pattern mode. This automatically loops horizontally and vertically to fill every square-inch of page columns with diagonal semi-transparent stamps, making unauthorized page copy or capture extremely difficult.
