Use at least four characters you can share with the recipient.

When to protect a PDF
Password protection helps when a file leaves your control but should not be open to everyone. Contracts, payroll, medical summaries, and financial exports are common examples.
LovePDF adds an open password. It is not the same as redacting content or removing metadata — review sensitive exports before sharing.
