Key Features
- Text Watermarks — Type any text including copyright symbols (©), brand names, URLs, or custom messages. Choose from 12 fonts: Arial, Georgia, Times New Roman, Courier New, Verdana, Impact, Comic Sans MS, Trebuchet MS, Palatino, Garamond, Lucida Console, and Brush Script MT.
- Image Watermarks — Upload a logo, stamp, or any image as a watermark. PNG files with transparency work best. The watermark image is automatically scaled relative to the font size control.
- Font Styling — Toggle Bold, Italic, Shadow (drop shadow for readability), and Outline (stroke around text) independently. Combine them for maximum visibility on both light and dark backgrounds.
- Custom Color — Full color picker for text watermarks. White with shadow is the classic choice, but any color works for specific brand requirements.
- Opacity Control — Adjust from 5% (barely visible, subtle protection) to 100% (fully opaque, strong branding). The sweet spot for protection is typically 30–50%, allowing the image to show through while making the watermark clearly visible.
- Rotation — Rotate the watermark from -180° to 180°. A -30° to -45° angle creates the classic diagonal watermark look that's difficult to crop out.
- 5 Position Presets — Center, Top-Left, Top-Right, Bottom-Left, Bottom-Right. Each position automatically adjusts text alignment and margins for clean placement.
- Tile Mode — Switch from single watermark to repeating tile pattern. Tiles the watermark across the entire image at specified spacing (50–400px). This creates the strongest protection as the watermark covers every part of the image.
- PNG Export — Lossless export preserving full quality and transparency.
- JPG Export — Compressed export at 92% quality for smaller file sizes. Ideal for web publishing and sharing.
Best Practices for Watermarking
- Protection Level — Use tiled watermarks at 30–50% opacity for strong protection. Single corner watermarks are easy to crop out.
- Readability — White text with shadow works on most images. For very light images, use dark text with an outline.
- Diagonal Angle — Rotate -30° to -45° for the classic professional watermark look that's resistant to cropping.
- Font Choice — Clean fonts like Arial or Verdana are most readable. Script fonts like Brush Script add elegance for creative work.
- Logo Watermarks — Use PNG logos with transparency. Set opacity to 30–40% for subtle branding.
