    How to use the Password-Protect ZIP

    1. 1

      Add the files or folder.

    2. 2

      Type a strong password (12+ characters).

    3. 3

      For maximum privacy choose 7Z and tick Encrypt file names.

    4. 4

      Create the archive and send it. Share the password through a different channel.

    AES-256 vs old ZIP passwords

    Many tools still use legacy ZipCrypto, which is easy to crack. We always use AES-256. Windows' built-in Explorer can't open AES ZIPs. Recipients on Windows should use 7-Zip, WinRAR or this site's extractor. iPhone's Files app opens AES ZIPs directly.

    Frequently asked questions

    Can I recover a forgotten password?
    No. AES-256 can't be bypassed. Keep the password safe.
    Are file names hidden?
    In ZIP, no. In 7Z with “Encrypt file names”, yes.
