Watermarking lets you claim ownership and protect your photos, artwork, and brand assets from unauthorized reuse. Add a discreet text copyright, your logo, or a repeated watermark, then tune the size, position, rotation, and opacity so it is visible enough to deter theft without spoiling the image.
Everything runs entirely in your browser using the HTML Canvas API. Your original image and watermark logo never leave your device, so sensitive and unpublished work stays completely private.
