Nowadays, a lot of PDF files do not allow copying, so many required text contents cannot be copied and edited into one's own document. That's not good, is it... However, with this little software, you don't need to worry anymore, haha^_^
It can remove the "prohibition of printing and editing" settings on PDFs, so you can copy any text content you like or need, and it also has a Chinese interface, making operation even more convenient.
