Unlock a password-protected ZIP
Have the password but want a copy without it? Drop your ZIP in, enter the password, and download an unprotected version. Works with legacy ZipCrypto and modern AES — all in your browser, never uploaded.
Why a ZIP needs its password
Unlike a protected Word or Excel file — where the lock is just a flag we can remove — a password-protected ZIP is genuinely encrypted. The only way to read it is with the password. So this tool unlocks a ZIP you can open: enter the password and we save a clean, unencrypted copy.
Forgotten the password? It can’t simply be removed — it has to be recovered by computation. That’s our pay-on-success recovery service (coming soon). The same applies to RAR and 7z archives, which this browser tool can’t open.
How it works
Everything runs in your browser using the open-source zip.js library. We read each entry, decrypt it with your password, and write a new ZIP with no encryption. Your files and folder structure are preserved exactly.
Is this legal?
Removing the password from your own archive, or one you’re authorised to access, is a normal task. Only unlock files you own or have permission to open.
Frequently asked
Is my file uploaded? No — it’s decrypted locally in your browser.
Does it support AES-encrypted ZIPs? Yes, as well as legacy ZipCrypto.
What about RAR or 7z? Not in the browser tool — those are routed to our recovery service.
