For most images, 20-40% opacity works best. This keeps your watermark visible while maintaining the image's aesthetic appeal. Higher opacity (50-70%) offers stronger protection but may be more distracting.
Your watermark should be readable but not dominating. Aim for 5-15% of the total image area. For high-resolution images, use larger font sizes (40-60px).
White watermarks work best on dark images, while dark watermarks suit lighter backgrounds. For versatility, white text at 30-40% opacity works across most images.
Use the same watermark style across all your images to build brand recognition. Include your copyright symbol (©), year, and name or business identifier.
