    How It Works

    1. Upload

    Drop any file — PDF, Word, Excel, ZIP and more. Max 100 MB. No account needed.

    2. Set Password

    Choose a strong password. AES-256 encryption is applied instantly on our server in-memory.

    3. Download

    Download your encrypted ZIP. Only someone with your password can open it.

    Security Best Practices

    1

    Use at least 12 characters with numbers and symbols (!@#$%)

    2

    Store your password in a password manager — we can't recover it for you

    3

    Files are processed in-memory only — never saved to disk on our servers

    4

    Encrypted files can be shared safely via email, cloud, or messaging apps

    All file types are packaged as a password-protected ZIP for universal compatibility.
