Open the workspace, protect the file, and download the result locally.

Open a .vault package with the original password and restore the file directly on your device.
Quick starts
Jump into a common file type when you want a tighter file match without changing the core workflow.
How it works
Add the file
Choose the file you want to protect, or upload an existing .vault package when you need to restore the original content.
Use a strong passphrase
Create a unique password and store it safely. The vault cannot be reopened without the exact passphrase used during encryption.
Download the result
Save the encrypted or restored file locally, then keep the password separate from the vault if you need to share it onward.
Visible FAQ
What does Cryptvert do?
Cryptvert encrypts files into password-protected .vault packages in your browser and decrypts those vaults locally back into the original file on your device.
Do my files stay on my device during the core workflow?
Cryptvert is designed so supported encryption and decryption happen locally in your browser, with the resulting file downloaded back to your device.
What file types can I protect here?
You can use the generic workflow for supported documents, archives, images, media files, and structured exports, and there are also format-specific pages for common file families.
What happens if I lose the password?
You need the exact password used during encryption to reopen a vault. If the password is lost, the encrypted file cannot be restored.
