A confidential stamp labels documents that contain private, internal or restricted information. It helps readers understand handling expectations at a glance. A diagonal watermark stamp is common because it remains visible while leaving the document text readable.

Frequently asked questions
Can I make the stamp semi-transparent?
Yes. The watermark template includes opacity controls so the document remains readable.
Does this secure the document?
No. It is a visual label only. Use real access controls for confidential files.
Legal & usage
A visual stamp is not access control. Use proper permissions, encryption and document handling policies for sensitive information.
