How to change a document on pdf?

Question

Is there any free (downloable) program to change/edit pdf files? Please tell me

Answer 1

You can try this free PDF editor:

If you want to edit text in a file though, PDF edit is a good open source product for Linux, see:

http://sourceforge.net/projects/pdfedit

Answer 2

I haven't found anything truly "Free".  I have been looking for something free or cheap also.  Be careful, I downloaded a cracked version of a .pdf editor and it corrupted my .pdf files.

So, just use caution.
