This is an essential feature for photographers, artists, and businesses to assert ownership, prevent unauthorized use, and promote their brand across digital platforms. The tool offers flexibility in design, allowing adjustments to position, size, and transparency.

Watermarking digitally modifies an image's pixel data to embed a visual identifier. For text watermarks, the tool renders the text onto a transparent layer, which is then composited onto the original image. For image watermarks (like logos), the watermark image is similarly composited. Options for opacity control the blending of the watermark with the base image. All operations are typically performed client-side using Canvas APIs, ensuring that original images are not uploaded to servers and user privacy is maintained.
