I need to upload lage size pdf files but it seems like i can upload upto only 2mb pdf files.

So where and How can i increase the limit of PDF files(size)?

admin panel >> configuration >> [left column menu] Attachment Types >> find pdf at right side and use edit control

note: in general, web hosts set maximum file size as 7MB for the attachments

All right

And is it possible to increase attachments limit form web hosts? (I have a unlimited space at my web host)

^ yes, contact the web host.
