Free AI Image Upscaler

AI Image Upscaler enlarges images with Topaz upscaling technology, adding detail instead of just stretching pixels. Upload a photo or illustration and get a sharper, larger version — useful when a generation needs to go to print or a small source image has to fill a big screen.

What it does

Bigger without the blur

Detail-aware enlargement

The model reconstructs edges and texture as it scales, so results stay crisp where naive resizing goes soft.

Works on any image

Photos, AI generations, illustrations, and product shots — PNG, JPG, or WebP up to 10 MB.

Built into the gallery too

Every image you generate on Nano Banana Lab has an Upscale button right in the results — this page handles files that come from elsewhere.

Frequently asked questions

The upscaler works at up to 4× the original size, with the factor configured by the site. Very small or heavily compressed sources upscale less cleanly than sharp ones.

Yes — it is the same Topaz upscaling used by the Upscale button in your generation results, and it handles AI output particularly well.

It sharpens and enlarges, which helps mild softness, but it cannot recover detail that was never captured — a heavily blurred photo stays imperfect, just bigger and cleaner.

PNG, JPG, and WebP up to 10 MB, via upload or a direct image URL.
