Want to unencrypt a secure PDF file, edit it and then re-encrypt it? Of course it's possible. Upload your documents with our PDF protection tool and they will be encrypted with a strong password. By policy, our service has no control over users' passwords and does not store them on our servers. So remember your new password or write it down in another document. Unfortunately, we cannot help you even if you need to know your password. It is recommended to create a password using a combination of letters, numbers, and special characters, not personal information such as address or phone number.
