editing in pdf files

how can we overwrite pdf files like we want to change or edit in pdf files so how is there any soure or way to overwrite in pdf files or can edit into pdf file

 

If you have the Adobe Reader, not possible. Look here for an editor.

 

Many Ways, but the editor plug-ins can be very expensive PitStop Pro is very good but is also very expensive. You can also import the PDF into Pagemaker or Indesign or Quarkxpress (with a free PDF filter xtension) just like any other piece of artwork and modify it the hard way by using filled white text boxes to cover up the stuff you don't want and re-distilling the PDF.

Or send it to a local print shop.

Or send it to me, for a fee ofcourse.
