Why lock a PDF
Emails can be forwarded and attachments can be saved on shared computers. A password makes sure that only someone with the key can read the content. This is important for bank papers, medical files, and legal documents.
Keep your password safe
Pick a password that is hard to guess and store it somewhere safe. If you lose it, the file cannot be opened. Share the password through a different channel than the file itself for better safety.
