Best PDF security tool for researchers

Why researchers need a PDF security tool

The PDF security tool tools researchers use most

• •Redact PDF: Redacting a PDF permanently removes the underlying text and images under a black box — not just covering them — so hidden data can't be recovered.
• •Password Protect PDF: Protecting a PDF encrypts it with a password, so only people with the password can open the file — the encryption travels with the document.
• •Unlock PDF: Unlocking a PDF removes a known password or usage restrictions from a document you own, so it opens and prints without prompting.
• •Remove PDF Metadata: Removing PDF metadata strips author names, software fingerprints, timestamps and hidden properties, so a shared file doesn't leak who made it or how.
