Any valid ImageMagick geometry argument form may be used at "size" property (see ImageMagick Image Geometry).

In default settings used ">" postfix:

> widthxheight> Shrinks images with dimension(s) larger than the corresponding width and/or height dimension(s).

If you would change --size - dont forget about right postfix!
