AI Image Upscaler

iThe Swin2SR super-resolution models are memory intensive. Avoid images larger than about 1000px on the long edge, or the browser tab may become slow or crash. All processing runs locally.

Drag or click to upload an image

Low-resolution images around 200px - 800px usually work best. Processing is done locally by AI.

Tool guide

Upscale images and inspect generated details

Choose a Swin2SR 2× or 4× model to process low-resolution images in the browser.

How to use

  1. Choose a small image and a model.
  2. Start processing, inspect text, faces and edges, then download.

Example and expected result

Size example: a 400×300 image with a 2× model → 800×600.
New textures are model estimates, not guaranteed original details.

Capabilities and limits

  • Higher resolutions require substantially more memory and time.
  • Original detail is not guaranteed; artifacts may appear.

Troubleshooting

Check the network for model-download failures. Reduce dimensions for memory errors and avoid repeated upscaling of large images.

Data processing and storage

Remote models are downloaded, while a local Worker performs inference. Results enter image history and can be deleted there.
