mirror generator is a small web app that creates symmetrical versions of images using the HTML5 Canvas API.
Upload any image (or load the demo), pick a mirror mode, and save. Eight mirror modes are available: top, bottom, left, right, and the four corner quadrants (tl, tr, bl, br). Invert x and y axes independently to get 32 possible variations per image. Exports at the original image resolution.
Built with vanilla HTML, CSS, and JS — no dependencies.
