Output scale

AI rebuilds details at 4× first. A 2× output is then downsampled at high quality.

PNG and WebP preserve transparency. WebP uses high-quality compression.

The first run loads a ~4.6 MB model and ~26 MB runtime. The model is cached when storage allows and reused on later runs.

Your device does the work

No image uploads, account or cloud quota. The model and runtime load from this site; decoding, inference and export all happen inside your browser.

Speed depends on your device

Auto mode tries the GPU first and falls back to CPU. Larger images take longer. Start with a small image and keep this page open; you can cancel at any time.

More pixels, inferred details

AI predicts textures and cannot guarantee faithful restoration. Text, faces and severely blurred images may change. Review the comparison before saving. Animated images use only the first frame.
