Two tools that sound alike and fix different problems.
When to upscale
The picture looks fine on screen but is too small for what you need: a print, a banner, a large display or a close crop. Upscale in Melon Cut Design enlarges it 2× or 4×.
When to enhance
The picture is big enough but looks soft, noisy or blocky - often after it has been compressed or saved several times. Enhance details in Melon Cut Design improves texture and sharpness and cleans up those artifacts.
Using both
For a small, rough picture, enhance it first so the upscaler starts from clean detail, then upscale it. Both tools work on up to 8 pictures in one request.
