What is a PDF Watermark
A watermark is a recognizable pattern or image that is superimposed onto a PDF document to indicate its authenticity or provide additional information.
Watermarks can serve various purpose:
- indicating the document's status,
- preventing unauthorized copying or distribution,
- adding branding elements to the PDF, etc.
They can be visible, appearing as text or an image that overlays the document content, or they can be semi-transparent, allowing the underlying content to remain visible.
PDF editing software often provides features to add watermarks, enabling users to customize their appearance, positioning, and other properties.
Watermarks are commonly used in industries where document integrity and security are essential, such as legal, financial, or government sectors.
