REDUCE FILE SIZE with Acrobat Pro

Hi everyone!

I  created a epk for a rock band  with Illustrator then I created one pdf that contains the all three pages with Acrobat Pro (I downloaded the trial because it was just for this occasion) This epk is a pdf file with 3 pages, some pictures and hyperlinks.

I need to send the epk to the band and they want a reduced size one. The original is 8.3 M but obviously it's too big to be sent via email.

I have been trying with the option SAVE AS -  REDUCED SIZE PDF but it doesn't work! Still the same size.

I am new to acrobat so maybe I am missing something.

HELP!

Thanks
