How it works
- Open your ZIP. Drop it on the page or pick it from your files. Only the file list at the end of the archive is read, so even big archives open in a moment.
- Look inside. Fold and unfold folders, filter by name, and preview text files or pictures before you save anything. Password-protected files are clearly marked.
- Save what you need. Save one file, tick several and save them, save everything as separate files, or repack your selection into a new, smaller ZIP. Only the files you ask for are decompressed.
Questions, answered
Are my files uploaded anywhere?
No. Unzip Files Online runs entirely in your browser. Your ZIP is read on your device, decompressed with JavaScript, and never sent to a server. You can disconnect from the internet and it keeps working, which makes it safe for bank statements, exported data or anything else private.
Can I unzip files on an iPhone, iPad or Chromebook?
Yes. It works in Safari, Chrome, Edge and Firefox on phones, tablets, Chromebooks and locked-down work laptops where you cannot install an archive app. Very large archives (over about 1 GB) may run out of memory on phones, and the tool warns you before that happens.
What about password-protected ZIPs, RAR, 7z or split archives?
Encrypted entries are listed and marked as password protected, but this tool cannot open them; use a desktop app such as 7-Zip with the password. RAR, 7z, self-extracting .exe files and split archives (.z01, .zip.001) are recognised and explained instead of failing silently. Only regular ZIP files, including ZIP64, can be extracted.
Is it really free?
Yes. It is open source under the MIT license, with no account, no file size limits, no ads and no fake download buttons. If it saves you a paid subscription, you can say thanks on Ko-fi.
Does it work offline?
Yes. After your first visit the page is cached by a service worker, so it loads without a connection. You can also install it from your browser's menu as an app.
Was this written by AI?
Yes. Unzip Files Online was generated by Claude Code from a written specification inside an automated pipeline, with a test suite that runs in a real browser. The full source is on GitHub, so you can read every line before you trust it with your files.
