The result depends on who you want to make it smaller.
By size (number of pixels), by quality (-quality factor),
by compression (depending on the image format) and the image format
itself.
IM has no way of predicting how big a file will be except by actually
trying it. No image problem can pre-determine this in any exact way
as there are just too many factors that need to be considered.
So basically if you want a particular size, then write a script to
adjust the factors you want to change so as to try and achieve the
result you want.
