However, many times we may set password protection in PDF files, resulting in the inability to access or edit the file content normally. So, how to effectively remove password protection from PDF files? Today, PHP editor Youzi will share with you some practical methods and techniques to help you easily remove the password of PDF files, allowing you to process and use files more conveniently.
Today we will take a look at how to cancel the two passwords of PDF, namely "restriction password" and "open password", and how to deal with the situation of forgetting the password.
