Another useless website for you? (The NicoNico ones weren’t too useless) Well this one is. I don’t know what the point is or what you could do with this.
Also, if you get the error: エラー: 申し訳ありませんが，画像が大きすぎるようです(;_;) that means your image is too large! Just resize it or find a smaller, okay? I got that error a bit, figured it might help to share what it meant.
Useless, but maybe worthy a few tries. Website is here.
