They add a password before emailing. A law firm shares discovery documents with opposing counsel but wants to prevent them from printing or distributing copies. They apply printing restrictions. An HR department emails offer letters to new hires and wants to protect personal information during transmission. They password-protect each document.

Types of PDF Protection
When you protect pdf, you have several security options. User password (also called open password) requires anyone to enter a password just to open and view the document. This is the most common type of protection. Owner password (also called permissions password) controls what users can do with the document after opening it. You can restrict printing, editing, copying text and images, adding comments, filling forms, and more. You can combine both types for maximum security. Our tool supports 128-bit and 256-bit AES encryption, which are industry standards for document security. You can choose the encryption level based on your security needs.
Password Best Practices
To effectively protect pdf, strong passwords are essential. Use a mix of uppercase and lowercase letters, numbers, and special characters. Avoid common words, names, or easily guessable information. Longer passwords are more secure aim for at least 8-12 characters. Never use the same password for multiple important documents. Store passwords securely, preferably in a password manager. Remember that if you lose the password, there is no way to recover it even for us. Our tool does not store passwords or have any backdoor access. Also consider that password protection is strong, but no security is absolute. For extremely sensitive documents, consider additional security measures like encrypted email or secure file transfer services.
