Encrypt files with AES-256-GCM before sharing. All encryption happens in your browser. Select a file you want to encrypt by clicking the upload area or dragging a file onto it. Enter a strong password that will be used to derive the AES-256-GCM encryption key. Click "Encrypt" to encrypt the file entirely in your browser using Web Crypto API. Download the encrypted file to share securely — the recipient needs the password to decrypt it.
