Protect ZIP puts a password on a zip. Add loose files, a whole folder or an existing zip, choose a password, and download a zip whose contents are encrypted with AES-256, the strongest encryption the zip format supports. Unlock ZIP does the reverse for a zip whose password you know: you get the same files back in a zip that opens without one.
People protect a zip before emailing payslips, bank statements or client records, and before copying a folder to a shared drive or a USB stick. Unlocking is useful when a bank or a colleague sends a protected zip and you want to open it with the zip tool built into your computer, or keep it in a place where typing the password every time is a nuisance.
Two honest limits. First, a zip keeps its file names and sizes visible; only the contents are encrypted, so use Encrypt File when the names themselves are private. Second, AES zips open in 7-Zip, WinRAR, WinZip, PeaZip, Keka and most phone file managers, but not in the zip tool built into Windows Explorer or macOS Archive Utility. Unlock ZIP cannot open a zip whose password you do not know, and it never tries to guess one.
The rest of the article, and all 6 questions about Protect ZIP / Unlock ZIP, are on the Protect ZIP / Unlock ZIP page.
Choose Protect, add your files, a folder or an existing zip, type a password of at least 8 characters, confirm it, and click Protect. The download is a zip encrypted with AES-256 that asks for the password when opened. No signup, no upload, no watermark.
No. Unlock ZIP only works with a password you already know. It does not crack, guess or bypass passwords and never tries. If the password is lost, ask the person who made the zip to send the files again.
The zip tool built into Windows Explorer and macOS Archive Utility only understand the old ZipCrypto scheme, which is easy to break. AES-256 zips need 7-Zip or PeaZip on Windows, Keka on macOS, or most file managers on Android and iPhone. Or unlock it here with the password.
No. In the zip format, file names and sizes stay readable; only the contents are encrypted. If the names themselves are sensitive, use Encrypt File, which hides the name inside an encrypted .enc file, or give the files neutral names before zipping.
