how can i make the size of my document that i created smaller so that i can email it easier

The 5 page document I created and need to send is 1.7MB.  I need it to be 250KB to send using the format requested.  All the info needs to be sent.  How can i shrink the data by such a large amount to enable the document to send?  I am on Windows 7 and using AcrobatXI
