Change Password on PDF
As users pay more attention to privacy, more and more people choose to add passwords to PDF documents to protect the documents from being accessed. However, in addition to setting an initial password, you often have the option to change the password when sharing a document with a third party, suspecting that the current password has been compromised, or to keep file security up to date.
But compared to adding a password, changing it can be a bit more challenging. This article will explore two available methods to change PDF passwords, one free and one online, to suit the different needs of users.
