Choose a larger output resolution

Select a model that offers 2K or 4K and pick the available resolution in the workspace. The model recreates fine detail, so compare faces, textures and lettering at full size.

When this helps

A small product photo may need a 4K version for a new crop. Inspect its label at 100% before treating the larger file as a faithful source.

How to use it

  1. Upload a clear original image.

Questions about AI Image Upscaler

Can I choose a fixed 2× or 4× multiplier?

Choose a supported resolution in the workspace. The exact dimensions depend on the model and ratio, so inspect the downloaded file for the required size.

Which models can output 4K?

Nano Banana 2 and Seedream 4.5 offer 4K in the current model catalog.

Will the model preserve text exactly?

Generation can recreate characters or edges. Keep the source artwork or reapply exact lettering in an editor.

What should I check before using an upscale for print?

Choose a model with the resolution you need, then view text, faces and repeating patterns at actual size. A larger file can contain newly inferred details. Keep the original for work that requires exact text or documentary fidelity.
