PDF documents can sometimes be encrypted, but after encryption, the password is forgotten. At this time, it becomes particularly urgent. I believe many people want to know how to crack it. Below, the editor will tell you!
1. Firstly, it depends on whether your document has added printing restrictions or is truly encrypted. The difference between the two is whether a password is required to open and view the document.
2. If you don't need it, congratulations. 99% can be broken, just remove protection and lift the editing permission security restrictions.
3. If a password is required to open a document, it depends on whether there is a document password. If so, use the same software as above to crack it, but choose the password recovery function. This software requires a lot of time to crack the password, which may take a few minutes or even several days.
The above is the password cracking technique for PDF documents that I have brought to you. I hope it can be helpful to you. If you have any questions, please feel free to leave a message to me.
