See it on your own image.

Drop in a piece of art, then move a lens over it to compare a normal resize with RezUp, up close. It runs on your own computer: your image is never uploaded.

This browser demo is much slower than the app. So it sharpens only the spot under the lens, a few seconds at a time. The app does a whole image in about 25 seconds on a modern laptop.
