See http://www.imagemagick.org/script/command-line-options.php#resize
To resize to some specific dimension, such as 600x300, use
convert rose.jpg -resize 600x300\! rose1.jpg
Also from your message about getting 50x50 from a 1280x960 image,
perhaps your image size is not what you think. Also be sure you do
not have a space between 50 and %, ie, it should be 50% and not 50 %.
JPG format is lossy and not a good format for trying to get exact
file sizes in bytes as a result. You can control (but not specify
exactly) the resulting file size by using the -quality option before
the output. See

Hi,
Thanks
We are trying to reduce a .jpg file to 50% of its original size
We have a rose.jpg which is 1280 * 960
If we use
Convert rose.jpg -resize 50% rose1.jpg.
It reduces the dimension to 50 * 50, is there a way to reduce this this
600 * 300....I mean can it be possible reduce exactly by some %.
