How Image Watermarking works
The Image Watermark tool adds text or image watermarks to your photos to protect intellectual property and establish ownership. Customize the watermark text, font, size, opacity, and position, then process images entirely in your browser for complete privacy.

Common mistakes
- For maximum protection, use a tiled semi-transparent watermark at 15-25% opacity. Place it diagonally across the image \u2014 this makes it difficult to crop out while remaining unobtrusive to viewers.
