No image upscaled yet
Upload an image to upscale it.
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
The model reconstructs edges and texture as it scales, so results stay crisp where naive resizing goes soft.
Photos, AI generations, illustrations, and product shots — PNG, JPG, or WebP up to 10 MB.
Every image you generate on Nano Banana Lab has an Upscale button right in the results — this page handles files that come from elsewhere.

Open the editorThe 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.
