PDF size

Hello,

     I've an application that shows a report that it's split in different files in pdf format.

For example, I've a report with 14 pages that is shown through an url like http://ipaddress:port/reports/rwservlet/getjobid=XXX, that it could be saved in pdf format. Then this report is split in 14 pdfs files that are uploaded to database and sent by mail.

The problem is that if I save the whole file from http://ipaddress:port/reports/rwservlet/getjobid=XXX its size is 839KB and the size of every separated file is about 815KB, that if I sum the size of the 14 files is about 11.5MB!
