can pdf files be converted to text?

I don't know how to read PDF files and I see them a lot when trying to research 
something on the Web.  Even my daughters' school calendar is now set up that 
way so I can't read it.  I am using jaws 7 and 6.20 depending, and XP home.  Is 
there a way to convert PDF documents to plain text so I can use normal Jaws 
commands?  If not, is there some sort of Adobe or PDF tutorial available?  
Thanks.
