PDF encryption

PDF encryption is a security measure used to protect the contents of a PDF file. It restricts access to the document by requiring a password to open or modify it. There are different levels of encryption: some allow viewing but limit printing or editing, while others completely lock the file. This ensures that sensitive information remains confidential, as only authorized users can access or alter the file. Encryption helps maintain privacy and integrity in documents shared electronically, making it a crucial tool for individuals and businesses alike.
