Ask for a password to open the ZIP

Password

Encryption AES-256 (recommended)Strong. Opens in 7-Zip, WinRAR, Keka, The Unarchiver, macOS Archive Utility on recent versions, Linux, and most phone apps. Windows Explorer can’t open it. Standard ZipCrypto (max compatibility)Opens in Windows Explorer and everywhere else, but the encryption is weak. Use for convenience, not for sensitive data.

Output is a standard .zip (Deflate), compatible with all major platforms.

This free tool zips a whole folder into a standard ZIP file and lets you add a password before download. Everything runs inside your browser tab, so your files are never uploaded. Choose AES-256 for strong protection or ZipCrypto for maximum compatibility.

What Is a Password-Protected ZIP Folder?

A password-protected ZIP is a standard .zip archive whose contents are encrypted with a passphrase. Anyone who knows the password can open it with common tools such as 7-Zip, WinRAR, Keka, macOS Archive Utility or Windows Explorer (ZipCrypto only). AES-256 gives real protection, while ZipCrypto is weaker and best for casual convenience, not sensitive files.

How to Use This ZIP Folder Tool?

Drop a folder or select files, toggle Password protect, then type a password and pick AES-256 or Standard ZipCrypto. Press Create ZIP and wait for the progress bar to finish. The archive downloads straight from your browser as a normal .zip, ready to email, share or store.
