About this tool
The watermark is drawn straight onto a copy of your image on an in-browser canvas, so what you see in the preview is exactly what downloads. Use a light color at partial opacity for a subtle mark, or full opacity and a dark color for something that stands out. The "repeat" option tiles the text diagonally across the whole image, which is harder for someone to crop out than a single corner stamp.
