Make a small image big enough to use. Upload low-resolution cover art or a press photo and the AI enlarges it to 4K while rebuilding edges and texture instead of just stretching pixels.
Upload the image and generate. Download the enlarged 4K version when it finishes.
It sharpens soft images and adds resolution. Heavily damaged or very old prints do better in Photo Restoration first.
