Why PrintGuard is the safer way to print confidential documents
Many people use print shops for documents like passports, bank statements, legal forms and medical letters. These documents should not be exposed to the shop's computer, network, or backup systems.
PrintGuard protects your file by encrypting it in the browser before upload. The print shop receives only unreadable ciphertext and a job code. The file is never stored in plaintext on the server or on the shop's device.
What makes it secure
- Encryption happens locally in your browser with AES-256-GCM.
- The server stores only encrypted ciphertext, not the raw document.
- Decryption happens on the shop's browser using your passphrase.
- Files are deleted automatically after printing or after one hour.
What users gain
- No account or personal information is required to use the service.
- Your document cannot be read by us, the print shop, or any server.
- Passing the code and passphrase separately keeps the workflow private.
- The service is designed for convenience and stronger privacy together.
The goal is to show that PrintGuard is a real service with a clear privacy promise. This is not just a form page — it is a tool built to protect sensitive documents in real-world printing situations.
Who should use PrintGuard
PrintGuard is ideal for anyone printing confidential files through a third-party shop. It is especially useful for passports, bank statements, contracts, medical records, and other sensitive documents.
- People who want to avoid exposing documents on the shop's computer.
- Small businesses printing invoices, contracts, or tax documents.
- Patients who need secure printing for medical or health records.
- Anyone who wants strong privacy without creating an account.
The encrypted file and passphrase are kept separate, so the shop can print without ever reading the contents of your document.
