About Image Watermark
This tool adds a repeating, semi-transparent text watermark across your image to help protect it from unauthorized use — useful for portfolio photos, product images, or draft documents shared online. The watermark is tiled diagonally so it's difficult to crop out without damaging the image. All rendering happens locally via the Canvas API; nothing is uploaded.
