About this seal
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.
Common uses
- Internal reports and financial packets
- Draft contracts and board materials
- HR, legal and compliance documents
- PDF overlays for sensitive files
How to create it
- Open the template — CONFIDENTIAL is pre-set as a watermark seal.
- Adjust opacity so underlying text remains readable.
- Choose red, gray, blue or another handling color.
- Tune rotation and export as a transparent PNG.
- Place it with the PDF stamp tool when needed.
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.
