The commercial Adobe Acrobat Std/Pro/Premier (whatever they're selling 
now) program can do this on windows, if the PDF files were created in 
such a way to allow you to convert them back to text or doc files. If 
the PDF files were created with security, encryption or copyright access 
controls, you may not be able to do this at all.

There are other methods of manipulating pdf files on linux & the 
OpenOffice-Writer program is one of the best. See also,

It is important to understand what a PDF is 
<http://en.wikipedia.org/wiki/Portable_Document_Format> & why it is used 
to distribute copyrighted content, retaining it's original formating, 
fonts and layout. PDF documents are created by printing to a pseudo 
printer device and rasterizing to postscript the content including the 
formating, so the .pdf file is simply a electronic printout of a 
document without the paper. This makes it possible to distribute .pdf 
files that can display content created using commercial  fonts with out 
having to install the proprietary fonts on client systems. To reverse 
the process is much more difficult and likely will not retain the exact 
formatting and fonts once it is converted to a .txt, .doc, or odp file.
