Upscale images
2× or 4×.
Drop a low-resolution photo — get a sharp, high-res PNG. Powered by Swin2SR.
Upscale factor
Input is capped at 4 megapixels on CPU to keep runtime reasonable. Output will be 2× the (possibly downscaled) input.
Useful since 4× can take a few minutes on CPU.
Images are processed on our servers and deleted within 1 hour.
Swin2SR open-source model
The same architecture family as Swin Transformer, fine-tuned for real-world photos.
2× or 4×
2× is fast (~60s on CPU). 4× uses the realistic-photo BSRGAN-tuned variant for detail.
