What is Image Watermark Tool?
Image Watermark Tool places custom text over photos and graphics for ownership, attribution, drafts, and branded sharing. Set the text, position, color, size, opacity, and tiling behavior before export. The watermark is composited in the browser and becomes part of the downloaded image.
How does Image Watermark Tool work?
This tool decodes the image, draws it to canvas, and renders watermark text on top using the selected style settings. Because the text is merged into the pixels, the exported image contains the watermark as visible image content.
