What is a Watermark?
A watermark is a semi-transparent text or image overlay placed on a photo to indicate ownership, copyright, or branding. Photographers, designers, and businesses use watermarks to protect their work from unauthorized use while still allowing people to preview the content.
How Does It Work?
This tool runs entirely in your browser using the HTML5 Canvas API. When you upload images, they are loaded locally — nothing is sent to any server. The watermark is rendered onto a canvas element in real-time as you adjust controls, then exported as a standard image file. Your privacy is always protected.
Text vs Image Watermarks
Text watermarks are ideal for quick branding — add your name, website URL, or copyright notice in any font, size, and color. They adapt well to images of any size and are easy to customize.
Image watermarks are best when you have a logo, badge, or signature graphic. Upload your watermark image once and apply it consistently across all your photos with precise control over scale and opacity.
