This site suggests several pieces of software (both paid and freeware) which will compress a pdf file. Note - the freeware solutions require that you have Ghostscript installed. For non-commercial use, Ghostscript offers a free open source license.

hi Rebel..
thank you..but i don't understanding Why i need Ghostscript & how to use it?

Ghostscript is a utility that software developers can use to work with PDF files, so that they don't have to create a PDF tool from scratch.
You can download it from the link provided by Rebel, then install it. It will be use by PDF compressors mentioned in Rebel's first link under 3. Windows PDF Tools.
