The created pdf file gets to large


I would be very thankful if someone could help me with an issue of mine. When I create a pdf  from word format the new file gets to large. I have tried to alter the resolution (dpi) and a number of other things in the option menu but the file still get a size of 1,l6 Mb no matter the settings. I would like the file to be no larger than 200-300 Kb. Does someone please know how to to help me?
