That's quite a lot of pages! Must have taken ages to convert, too.

File sizes will be comparable to the source PDF if it mostly consisted of graphics, otherwise it can be expected to be in the order of 2-3 times the PDF. However, I've tried this mostly with small PDFs (300-400 pages). Some possibilites on reducing file size:
  • reduce the colors used to 2 (ie. monochrome). You can do this currently by customizing the profile
  • Use the portrait mode (should result is lesser pages)
  • optimize the PNG using optipng (extra processing step, not yet implemented)

Can you try #1 and #2 above?
