But these can be edited by converting once again into necessary format and even back to image too. There are specific tools which the user needs to install for editing the digital documents. 
The reason why we need digitization is that 
a) We want to convert hard copy into soft copy and store it in system.  
b) We would like to edit the data in the hard copy and preserve as a fresh copy.
