Unlock a password-protected ZIP
Choose the .zip you want to remove the password from.
Remove a ZIP password, in your browser
This tool takes a password-protected .zip that you can already open, decrypts it with the password you provide, and writes a new .zip with the same files and folders but no password. Use it when an archive keeps prompting for a password you know and you would rather keep a plain copy — for a colleague, a backup, or a program that cannot handle encrypted ZIPs.
It is not a password cracker. You need the correct password; the tool cannot open an archive whose password you do not know. Decryption and re-packing happen entirely in your browser, so the archive and the password never go to a server.
Why your file and password stay on your device
Privacy here is structural, not a promise. The decryption runs in your browser because there is no server to send anything to:
- The archive is decrypted and re-packed entirely in your browser.
- The page is served as static files and makes no request carrying your ZIP or your password.
- The source is open and anyone can read it (MIT).
- It works offline, which is only possible because nothing leaves the device.
If you want to check for yourself, open your browser's Network panel while unlocking — no request carries your file or password. Read the source.
How to use it
-
Choose your ZIP
Click to select the password-protected .zip, or drop it anywhere on the page.
-
Enter the password
Type the password you already use to open the archive. It is used only in your browser, to decrypt the files.
-
Download the unlocked copy
Select “Remove password”. A new .zip with the same contents downloads — and it opens with no password.
FAQ
Is my ZIP or password uploaded anywhere?
No. Decryption and re-packing run entirely in your browser. There is no server component, so neither your file nor your password has a path off your device. You can confirm this in your browser's Network panel.
Can this open a ZIP if I do not know the password?
No. This is not a password cracker or brute-forcer. You must enter the correct password — the same one you already use to open the archive. Without it, the encrypted files cannot be read.
How is this different from a ZIP extractor?
An extractor unpacks the files onto your device. This tool instead gives you back a .zip — the same files and folder structure — but with the password removed, so you can share or store an unprotected archive.
It says the ZIP is not password-protected. Why?
The archive has no encrypted entries, so there is nothing to remove. A file can seem “locked” only because a program asked for a password when opening it; if the entries were never encrypted, the ZIP is already unprotected.
Does it support AES and legacy ZipCrypto encryption?
Yes. It reads AES-encrypted ZIPs (the modern standard, e.g. from 7-Zip or WinRAR) as well as the older ZipCrypto scheme, as long as you supply the correct password.
Does the output keep my folders and file dates?
Yes. The unlocked .zip preserves the original folder structure and each entry's modification date; only the encryption is removed.
Does it work offline?
Yes. It is a PWA. After the first visit it is cached, so unlocking works without a network connection. You can also install it to your home screen.
