png is already a compressed format. There's no way to compress it
further within swf, unless you switch to lossy compression.

My guess would be that develotec.com's png2swf converts the image to
jpeg before storing it. It'd have to have a look at one of their
converted files to be sure.
If that's what they're doing, you can get the same result by converting
your image to jpeg, too, and then using jpeg2swf.
