A tool for compositing another image on top of your image. The overlay can be moved, scaled, rotated, flipped, and have its opacity adjusted, and you can place several at once. Great for adding a logo or watermark, or for making a collage.
To use it, first load a base image, then add the images you want to overlay and set their position and size. Lower the opacity to blend an image in like a watermark. The result can be downloaded as PNG, JPG, WebP, GIF, or ICO. Your image is never sent over the internet - everything is processed in your browser, so it stays safe.
