Frequently Asked Questions (Security & Protection)
How do I password-protect a PDF document online?
Upload your PDF to Protect PDF, type your chosen password, and click Protect. The document is encrypted with strong AES-256 over an encrypted TLS connection and deleted automatically once processing finishes.
Can I permanently black out / redact private information in a PDF?
Yes, our Redact PDF tool removes underlying text streams and object data completely inside your browser so redacted information cannot be selected or retrieved.
