how to unencrypt pdf file on windows and mac
To protect data security, we add password to protect the file. We can add the user password to open the PDF file, or use the administrator password to make access limitations, such as printing and editing.
Common reasons of PDF decryption
Reason 1: The encrypted PDF file cannot be printed.
Reason 2: The PDF file has to be opened with the correct password.
Reason 3: It feels trouble to enter the password for each use.
How to unencrypt PDF files? We should use the professional PDF decryption/editing software, or draw support from the online PDF password cracker. But the installed application is recommended because it offers various functions and it processes files much quickly than the online tool. Usually, the uploaded file size is limited in the online cracker, and it is not safe enough to upload the confidential PDF file to the website.
