How Watermark PDF Works
Why Use Watermark PDF?
Tips & Best Practices
- 1Use 'CONFIDENTIAL' or 'DRAFT' for common document watermarks; customize text for your organization's specific needs
- 2Lower opacity (20-40%) creates subtle watermarks that don't obscure content readability while still protecting documents
- 3A 45-degree rotation is the most common and readable watermark angle; it's diagonal and professional-looking
- 4Center position works best for most documents as it ensures visibility on every page regardless of content
- 5Use gray color for professional-looking watermarks; it's subtle yet visible on most document backgrounds and colors
- 6Higher opacity (60-80%) creates more visible watermarks that deter unauthorized copying; adjust based on your needs
