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

  1. Open the template — CONFIDENTIAL is pre-set as a watermark seal.
  2. Adjust opacity so underlying text remains readable.
  3. Choose red, gray, blue or another handling color.
  4. Tune rotation and export as a transparent PNG.
  5. 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.
