Frequently asked questions
How is this different from the Image Enhancer or Image Resizer?
They stretch existing pixels with classic filters. The upscaler uses a neural network trained to add realistic detail, which usually looks sharper on photos.
Is my image uploaded?
No. The model (about 5 MB) is downloaded once from this site and everything runs in your browser.
