Extracted pdf files sizes remain almost the same as original

I have an approx 300mb single PDF of thousands of pages. When extracting 100 pages using pdfarchitect latest version the 100 page document comes in at 298mb or so.  I was expecting maybe 8- 12 or so.  Any ideas or is this all pdfarchitect can do? Maybe it is just hiding the view ability of the other pages?  

Hi,


it does depend on the amount of fonts which need to be embedded, we haven’t been able to reproduce this here so far.
