HOW TO EDIT PDF FILES IN THIS PROGRAM

[Gonzalo Mamani]

Hello Friends, I found the program by chance and I already downloaded it, it seems wonderful EXCEPT because it only loads image files, I mean it only prepares the files as JPG PNG or any other image file. I look for a program that does exactly what this program does BUT FOR existing PDF FILES. I mean a program that can load pdf files and edit them in the same way that I edit JPGs because I do not scan new books. I want to FIX PDF books.

Is there any way of doing this? Any suggestions?
