Why add a watermark to PDF
A PDF watermark helps clearly communicate a document’s nature or intended use without obscuring the content.
Adding phrases like CONFIDENTIAL or SAMPLE or a company logo makes it easy to see at a glance how widely a document may be shared.
- You can easily distinguish confidential documents.
- It can reduce misuse or unauthorized use.
Difference between text watermarks and image watermarks
Text watermarks are great for light markings or confidentiality phrases, while image watermarks are better for emphasizing logos or brand elements.
You can choose either method depending on your document’s purpose.
- Text watermark: for markings like SAMPLE, CONFIDENTIAL
- Image watermark: company logo, brand mark
Why you should adjust position and opacity
Adjusting watermark position and opacity helps maintain readability while still achieving a clear marking effect.
You can place it diagonally in the center, in a corner, or at a custom location to match the document design.
- You can place it without interfering with document content.
- You can maintain visual balance.
Difference between watermarks and other security features
A watermark doesn’t block access to a document; it visually indicates the document’s nature.
When used together with password protection or text redaction, it can further strengthen security.
- Watermark: visual marking·branding
- Password·redaction: access restriction·content protection
