Who Uses Image Watermarks?
Watermarks are an essential tool for any creator sharing work online.
Photographers
Share portfolio samples and client proofs with your studio name or copyright notice prominently displayed.
E-commerce Sellers

Content Creators

Why Browser-Based Watermarking Is Better
Traditional watermarking tools require you to upload your original, unwatermarked high-resolution photos to a third-party server. This creates real privacy and security risks — your images may be stored, indexed, or accessed by the service provider.
By processing everything locally using the HTML5 Canvas API, this tool eliminates that risk entirely. Your images are rasterized and composited directly in GPU-accelerated browser memory, producing pixel-perfect watermark overlays in milliseconds without ever leaving your machine.
