💡Tips & Best Practices
- ✓Use semi-transparent watermarks (30-50% opacity) for professional-looking results that are harder to remove.
- ✓For image watermarks, upload high-contrast logos and use the transparent background option for clean results.
- ✓Tile watermarks across the entire page for maximum document protection.
- ✓A diagonal watermark can cover more of the page while keeping the document content readable.
