[Swftools-common] Why is the PDF original file smaller and the converted SWF so BIG???

[Clyde Sparks]

I'm using Windows version of PDF2SWF ver.0.6.3.

command= PDF2SWF -z -j35 0.pdf

input PDF ~140kbytes = http://www.clydesparks.com/test/0.pdf

output SWF ~1Mbyte = http://www.clydesparks.com/test/0.swf

Any ideas why the output is so big??
Can anyone suggest a way to make the output SWF smaller??

Thanks
