PDF is a good electronic document format at present, which has been widely used and has become a common format for many publishing houses to publish electronic versions. However, in the actual use process, it is found that many publishers encrypt PDF for different purposes, which makes the printing and copying functions of PDF documents invalid and makes it a little difficult for some users who want to print and copy documents. The following describes how to use advanced PDF password recovery to crack PDF documents so that they can be printed and copied.

Run the installed advanced PDF password recovery software, and it will be displayed in the "Status Window" that this is an unregistered version. Please click the "key" icon in the toolbar and enter the registration code.

Click the Open Document icon in the toolbar to open the encrypted PDF document. If the document is an unencrypted PDF file, it will prompt "File is unencrypted".

If the document is an encrypted PDF file, the prompt "This PDF file is protected. Do you want to remove the protection?" Just answer "yes".

Then the "Save the decrypted file as …" pop-up dialog box appears, select the location and file name of the saved file, and click "Save".

At this point, we can see the message "Protection has been successfully deleted" in the status window of advanced PDF password recovery.

At this point, the protection mark of the protected PDF has been successfully removed. You can use the corresponding PDF document reading and editing tools to open the above "Save As" document. Please see if you can print and copy.

A suggestion for software developers: One disadvantage of this tool software is that it has no batch processing function. When there are many PDFs to be deleted, you can only delete them one by one. If batch processing function and automatic naming can be provided, it will be more convenient for users. At the same time, I also thank the software authors for their hard work.

Note: If you want to restore the protection function of the PDF document, you only need to select Save As in Acrobat software, select Standard in the security part of the Save As dialog box, fill in the corresponding password in the dialog box that appears, and select the protected item. Opening a document is the password to open a PDF document, and changing the security is to modify its password.
