Does the checker upload my screenshot?

What does closest preset mean?

StoreHalo compares both dimensions and aspect ratio, then recommends the nearest supported export canvas.

Can I fix the screenshot after checking it?

Yes. Send it directly into a configured StoreHalo Studio project and continue editing there.
