About the Image Watermark Tool
ToolZeel's Image Watermark tool lets you protect your photos by adding text or image watermarks directly in your browser. Choose from 9 placement positions, adjust opacity and rotation for text watermarks, or overlay a logo with a custom size and opacity. The result is downloaded as a high-quality PNG file.
All processing uses the HTML5 Canvas API — nothing is ever uploaded to a server.
