a size from the pop‑up menu or enter a size in pixels. For Constrain, choose
which dimensions of the image you want to constrain during resizing. For JPEG
Quality, choose an option from the pop‑up menu, enter a value between
0 and 12, or drag the slider. The higher the value, the
better the image quality and the larger the file.

Bicubic Sharper as the default for best results when reducing image
size.
