Encryption and permissions explained.
What makes a strong PDF password?
Use at least 12 characters mixing letters, numbers, and symbols. Avoid words found in dictionaries.
Can recipients remove the password?
Anyone with the password can save an unprotected copy. Share passwords through secure channels only.
Will search engines index my file?

Does protection work on all readers?
Standard PDF encryption works in major viewers; very old software may have limited support.
