Image watermarking overlays text or a logo onto photographs to indicate ownership, prevent unauthorized use, or add branding. Photographers, stock image services, e-commerce businesses, and content creators use watermarks to protect their work while still being able to share previews. Watermarks can be subtle (low opacity, small text in a corner) or prominent (tiled across the entire image) depending on the level of protection needed.
In the age of easy screenshot-and-share, watermarking is the primary way to protect visual content. Photographers watermark client proofs before payment. Stock photo services watermark preview images. E-commerce brands watermark product photos to prevent competitors from using them. Social media creators add branded watermarks to maintain attribution as images get reshared. A well-placed watermark protects your work without ruining the viewing experience.
Upload an image and configure your watermark — text with customizable font, size, color, and opacity, or upload a logo image. Position the watermark using a 9-point grid (corners, edges, center) or enable tile mode to repeat it across the entire image. Adjust rotation for diagonal watermarks. The live canvas preview shows exactly how your watermark will look before you download. All processing uses the HTML5 Canvas API in your browser.
