Free PDF Password Protection — Encrypt PDFs Online

Our free online PDF password protection tool encrypts PDF documents with industry-standard AES encryption, requiring a password to open, copy, edit, or print the file. Secure confidential contracts, protect financial reports from unauthorized access, lock down patient records for HIPAA compliance, or password-protect personal documents — all in your browser without software installs or signups.

PDF encryption is essential for any document containing sensitive information: legal agreements, medical records, financial statements, intellectual property, internal corporate reports, and personal documents. Our professional PDF password tool uses 128-bit and 256-bit AES encryption — the same security standard used by banks, government agencies, and Fortune 500 companies — ensuring your protected PDFs cannot be opened without the correct password.
