I do not know of a way to reduce with the goal of changing the file
size. I can tell you how to batch convert files to a particular
resolution. Save this batch program and run to change images to 600
pixels wide jpeg quality 85. It will take all files you list on the
command line.
#!/bin/bash
for input in $@
do
base=`echo $input | sed 's/\(.*\)\..*$/\1/'`
## echo "SUF" $SUF "base" $base
suffix="600.jpg"
/usr/bin/convert $input -resize 600x -quality 85 $base$suffix
done
