Password protect an Adobe PDF

Password protect and encrypt your Adobe PDFs to ensure your privacy, protect your data, and secure intellectual or sensitive information. It is used to protect documents in transit (i.e. sent via email) and at rest (i.e. stored on a disk or in the cloud) from being accessed by unauthorized users. When you encrypt sensitive data, you severely decrease the risk of having it leaked. A hacker will not be able to make sense of your files.
