PDF file extremely enlarged when converted from ppt to pdf

I am trying to use slides for java to convert ppt to pdf with on linux. The conversion quality was great but the converted pdf is much larger than the original ppt, one from 230K to 27M, another from 6.5M to 31M.


The slides are in Chinese. The save options are:
savePdfOption.setEmbedFullFonts(false)
savePdfOption.setEmbedTrueTypeFontsForASCII(false)

The slides are originally in Chinese. I am using a licensed product.

What can I do to reduce the output size?

Thanks
