Image Watermark is a free online tool that lets you add text watermarks to your images directly in your browser. Protect your photos, graphics, and artwork by adding customizable text overlays with full control over position, font size, opacity, color, and rotation angle. The tool provides a real-time preview that updates instantly as you adjust the watermark settings. Choose from 7 position presets (corners, center, and edge centers) or rotate the text for diagonal watermarks. Adjust the opacity from subtle to bold, and pick any color to match or contrast with your image. All processing uses the HTML5 Canvas API entirely in your browser. Your images are never uploaded to any server, ensuring complete privacy for your original photos.
