Types of PDF Watermarks

There are different types of watermarks you can apply depending on your needs:

• Text Watermark: Simple text like "Confidential", "Draft", or company name.
• Image Watermark: Logo or brand identity overlay.

• Legal teams secure confidential files

Text vs Image Watermark – Which is Better?

Choosing between text and image watermark depends on your goal:

• Text Watermark: Best for quick labeling like "Sample" or "Confidential"
• Image Watermark: Best for branding and professional documents

For best results, use both strategically depending on document type.
