About UnzipIt

UnzipIt (unzipit.online) is a free online archive extractor that runs entirely inside your web browser. It lets you open and extract common archive formats such as ZIP, 7Z, RAR, TAR, GZ, TGZ, BZ2, XZ, ZST, CAB, ISO, JAR, APK and EPUB without installing any software and without uploading your files to a server.

The tool was built to solve a simple problem: most online archive extractors send your files to a remote server, process them there, and send the results back. That works, but it means someone else can see your files. UnzipIt does the same job without that risk.

We wanted a fast, private way to open archive files that does not require installing a desktop app or trusting an unknown upload site with sensitive documents.

Modern browsers now ship with WebAssembly and Web Worker support, which makes it possible to run a real archive engine locally — fast enough for everyday use, and private by design.

When you select an archive in UnzipIt, the file stays on your device. The extraction runs locally using JavaScript, a Web Worker, and a WebAssembly-based archive engine. The heavy work happens off the main UI thread so the page stays responsive.

The server only delivers the website itself — the HTML, JavaScript, worker, and WebAssembly files needed to run the tool. Your archive contents, extracted files, file names, and passwords never leave your browser.

Open and extract a wide range of archive formats, including ZIP, 7Z, RAR, TAR, GZ, TGZ, BZ2, XZ, ZST, CAB, ISO, JAR, APK and EPUB.

Open password-protected archives by entering the password locally in your browser.

Download individual extracted files, or save the whole extraction straight into a folder you choose (on browsers that support the File System Access API, such as Chrome and Edge).

UnzipIt is not a cloud storage service. There are no user accounts, no server-side file storage, and no sharing links.

UnzipIt does not scan extracted files for malware. Always open archives from sources you trust.
