What is the Password-Protected ZIP Creator & Extractor?
This site's existing ZIP Creator & Extractor is explicit that password-protected archives aren't supported — this tool fills that real gap using zip.js, a library that implements genuine AES encryption inside the standard ZIP format. Drop in files, set a password, and it produces a real .zip file that any standard archive tool (Windows, macOS, 7-Zip, WinRAR) will prompt for that exact password to open, because the encryption is written into the file using the real, standard ZIP encryption specification, not a custom wrapper.
The same tool also opens and extracts a password-protected ZIP you already have — enter the password, and every file inside decrypts and downloads, all processed locally so neither your files nor your password are ever sent anywhere.
3 steps to your result
Open the tool and follow along. Nothing to install.
What you get
Uses zip.js to write genuine AES-encrypted entries in the standard ZIP format any archive tool can open with the password.
One tool both builds a new encrypted archive and opens/extracts an existing password-protected one.
The resulting .zip opens correctly in Windows, macOS Archive Utility, 7-Zip and WinRAR, each prompting for the real password.
The plain ZIP Creator & Extractor explicitly doesn't support passwords — this tool exists specifically for that need.
AZRS tools are free to open and use.
It opens in your browser, so there is nothing to download.

Questions people ask
Is this real encryption, or just a password prompt?
Real encryption — zip.js implements genuine AES encryption as defined in the ZIP format specification, so the file contents are actually unreadable without the correct password, not merely hidden behind a UI prompt.
Will the encrypted ZIP open in normal archive software?
Yes — because it's written in the standard ZIP format with standard AES encryption, Windows, macOS Archive Utility, 7-Zip, WinRAR and other standard tools will open it and correctly prompt for the password.
Why doesn't the site's other ZIP tool do this?
That tool's own description states password-protected archives aren't supported; this is a separate, purpose-built tool specifically to fill that gap using a library capable of real ZIP encryption.
What if I forget the password?
There is no recovery — real encryption means the files are genuinely unreadable without the exact password, by design; store the password somewhere safe.
Is my file or password ever uploaded?
No — both creating and extracting happen entirely in your browser using zip.js; nothing is sent to any server.
