srikrishnan has asked for the wisdom of the Perl Monks concerning the following question: 

Hi All,

I am using "par" module for making "exe" file from my perl scripts. Us
+ually the size of the exe file is so big. I want to compress the exe 
+file size. Is it possible, what can I do for this?

Regards,

Re: Compress exe file size

    mod:/pp
    -z, --compress=NUMBER

    Set zip compression level; NUMBER is an integer from 0 to 9, 0 = no compression, 9 = max compression. Defaults to 6 if -z is not used.

    pp -z 9 -f PodStrip foo.pl

      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 ap
+proximately 500 to 700 KB only.

Can I make it reduce the exe size in such highly compressed way?

REgards,
Srikrishnan

        The difference is that pp generates a standalone application containing everything your script needs, including the entire perl interpreter and all required DLLs, whereas perlapp just wraps your script and a stub that loads the existing perl interpreter. The pp-generated EXE runs on a computer without perl, the perlapp-generated one doesn't.

        Choose what you need: If the target computer has your perl version installed, use perlapp. If it doesn't, use pp. Or even better: Distribute the raw script and a perl installer.

        (And by the way: The difference is not 7 bit, but 7 KBytes = 7 * 1024 Bytes * 8 Bit / Byte = 57.344 bits.)
