What is Document Encryption?

Document encryption is the process of converting your documents into an unreadable format that can only be restored with the correct password or key. This protects your sensitive documents from unauthorized access, ensuring that even if someone intercepts or steals your files, they cannot view the actual content.

Our free online document encryption tool uses military-grade encryption algorithms including AES-256-GCM, AES-256-CTR, AES-256-CBC, and XChaCha20-Poly1305 to protect your documents with the same level of security used by governments and financial institutions worldwide. Whether you're protecting personal documents, confidential business files, or sensitive financial data, our tool ensures your information remains private and secure.

Frequently Asked Questions

Is this document encryption tool free?

Yes, our document encryption tool is completely free to use with no limits on file size or number of encryptions. There are no watermarks, no sign-up required, and no hidden fees.

Are my documents stored on your servers?

No, absolutely not. All encryption and decryption happens on our secure servers during processing only. Your documents are never stored, logged, or saved anywhere. Once the encrypted file is downloaded, all data is immediately discarded.

Which encryption algorithm should I choose?

For most users, we recommend AES-256-GCM as it's the industry standard with excellent security and performance. If you want the latest modern cipher, choose XChaCha20-Poly1305. Both provide military-grade protection.

What happens if I forget my password?

If you forget your password, there is no way to recover your encrypted document. This is by design—it ensures that even we cannot access your files. Always store your passwords securely in a password manager.
