I have used ghostscript to reduce PDF files also.  I check the sizes of both files afterwards because ghostscript does not always make a smaller file.
It is probably better to add -c .setpdfwrite in the command line, for example
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/prepress -dNOPAUSE -dQUIET -dBATCH -sOutputFile=newfile.pdf -c .setpdfwrite -f myfile.pdf
