Hi, Thanks for your immediate reply. I have a perl script. when I convert using the following command: pp -gui -o xmpPDF1.exe xmpPDF.pl the resulted exe file size is "3,664 KB" when I use, as per you said: pp -gui -z 9 -o xmpPDF2.exe xmpPDF.pl the resulted exe file size is "3,657 KB" So it only reduced "7 bit". But when I create exe using "perlapp.exe", the size is very minimum approximately 500 to 700 KB only. Can I make it reduce the exe size in such highly compressed way? REgards, Srikrishnan
