Questions
Will a resized image look sharper?
Reducing dimensions can look cleaner, but enlarging cannot recreate detail that was not in the source image.
How do I avoid a distorted result?
Leave the ratio control linked. If you need a different shape, crop first instead of forcing a new width and height.
