Rebuilding detail, not stretching

Normal resizing stretches pixels and gets blurry; AI upscaling redraws edges and textures based on what it has learned.

2× is tuned for clean images (screenshots, graphics); 4× uses a model made for real photos with compression noise.

AI on your own computer

The model downloads once (a few MB to a few dozen MB) and is cached. It's fastest in Chrome or Edge on a computer with a graphics card, and photos are processed in small tiles to avoid running out of memory.

Frequently asked questions

How large can the photo be?

Up to 1,200 px on the long side for 2× and 640 px for 4×; larger photos are reduced first.

Will it change faces or invent content?

It's an enhancement model, not a generative one, so content stays the same. Very small text may not come back perfectly.

Is it paid?

No. It's free with no watermark.
