Remove a password you already know from a ZIP file, or try to recover a weak, simple one. 100% client-side: unlike most online zip unlockers, your file is never uploaded. It never leaves your browser.
Select a password-protected ZIP file. It opens in your browser's memory, and stays there.
Enter the password you already know and the ZIP is decrypted and repackaged without a password, using zip.js running entirely on your own device. No servers, no queue.
A fresh ZIP with no password is generated in the browser and downloaded straight to your device.
Most online ZIP unlockers ask you to upload your archive to their servers. We built this the opposite way: the code runs on your machine, so there is nothing for us to store, leak, or look at.
Only sometimes. If the ZIP uses legacy ZipCrypto with a short or common password, the free tool can attempt to recover it in your browser. But a modern AES-encrypted ZIP with a strong password cannot be recovered by any free tool, and we won't pretend otherwise. This tool is built to remove a password you already know.
Yes. Your file is processed entirely in your browser using zip.js. No file is ever uploaded to any server, and the tool keeps working if you disconnect from the internet after the page loads.
Yes, it matters a lot. Legacy ZipCrypto is weak and sometimes recoverable for short or common passwords. WinZip AES (AES-128/256) is strong: with a good password it is not feasible to recover. This tool removes any password you know, but only attempts recovery for weak ZipCrypto cases.
No. Everything runs in your browser - there is nothing to install.
No. The file is read into your browser's memory and processed there. It is never sent to a server.
Completely free - no sign-up, no upload, and no paid tier.
ZIP archives (.zip) only.
Most other sites upload your archive to their servers to process it. This tool runs zip.js entirely inside your browser, so your file never leaves your device.
This tool is provided for removing passwords from ZIP files you own or have authorization to access. By using this tool, you acknowledge that you are solely responsible for ensuring you have the right to modify the file. It cannot recover a strong, unknown password - a genuinely encrypted ZIP stays protected. Provided "as is" without warranty. The developers are not liable for any misuse.
