What is PDF Encryption?

PDF encryption password-protects your document, making it unreadable to anyone who doesn't have the password. FileKitPro uses industry-standard AES-256 encryption — the same level banks and governments use — to keep your sensitive documents secure.

When to Encrypt a PDF

Encrypt PDFs when sending confidential documents via email, sharing financial records or tax returns, distributing proprietary business documents, storing sensitive personal information, or any situation where you want to ensure only authorized recipients can open the file.
