I have a ~259 MB PDF. I did
ps2pdf. The final size was 45 MB. I don't see any visible difference in quality in any reader. Although, the bookmarks were lost. I tried using
pdftk, but it didn't preserve the bookmarks.
pdftk ... update_info
What caused the huge reduction in size? Is there an alternative to preserve the bookmarks and still have the reduced size (preferably linux command-line alternatives)?
