How to Split a large PDF file into smaller documents?

I am looking for a free tool to split a big (50 MB) PDF file into 10 small PDF files. Is there any way by using which I can break PDF file.



you could print the individual pages (or ranges of pages) into separate PDFs with the free version of PDFCreator.
The (not free) PDF Architect edit module has an improved GUI for this.

best regards,

Thank you so much Robin for the reply. 

Recently, I downloaded and used a free program for splitting PDF file into smaller parts. It works well for me.
