I always need to creat PowerPoint slides.
Most of my Powerpoint slides are about 20~30MB as they contain
a lot of pictures, graphs.
Usually, I save them as PDF files. The size of PDF file is smaller than ppt.
And it is more secure compare to PPT.
Anyways, when the slides are shared inside the organisation, PPT format is must.
sending out a (or a few)20~30MB PPT file is a painful, time consumed.
WinZip、WinRar does not help too much.

Today, I found a special software that can help me on this.
It is NXPowerLite. It can reduce the size of PPT files radically.
A 20MB PPT file can be reduce to 1.7MB after it is processed by NXPowerLite.
The quality of pictures and graphs look ok on the screen.
I have not try to print them out. I think the printing quality should be ok as well.

One more thing, NXPower can be run direactly as it is single, stand-alone
file that does not need to be installed

** Highly recommened

Platform: Win9x/Me/NT/2000/XP

Any idea how this product can reduce such large files so dramatically - without any obvious compromise on quality as you have reported - pardon my scepticism but it seems a little too good to be true. i will try it out however.
