What Is Image Watermarking?

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.

Why Watermark Your Images?

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.

How Does This Tool Work?

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.

Is It Safe?

Yes. Your images are processed entirely in your browser using the Canvas API. No photos are uploaded to any server. This is safe for client proofs, unpublished work, and any images you want to keep private while adding protection.

FAQ

Can I add a logo watermark?

Yes. Upload a PNG logo and it will be overlaid on your image with configurable size, opacity, and position.

What is tile mode?

Tile mode repeats the watermark across the entire image in a grid pattern. This is commonly used by photographers and stock photo services to protect image previews.

Can I watermark multiple images?

Yes. Upload multiple images and the same watermark settings will be applied to all of them.

Is this safe for my photos?

Absolutely. All processing happens in your browser using the Canvas API. Your photos never leave your device.
