ZIP Extractor — Unzip Files Online

Supported: ZIP
Your file is read and processed inside your own browser. It is never uploaded to our server, and it still works with the network unplugged.
How It Works
- Choose — Pick or drop your file into the area above. It stays on your machine unless this tool says otherwise.
- Configure — Set the options that appear once the file is read.
- Run — Press the action button and wait for the result.
- Take it — Download the output, or copy the result if the tool prints one.
Frequently Asked Questions
Are my files uploaded anywhere?
No. JSZip reads the archive in your browser and each entry is offered back to you as a local download; no request carries your file contents to a server.
What happens with a malicious archive?
Entry names are checked before anything is offered for download: parent-directory segments, absolute paths and drive letters are rejected, and symlink entries are refused. Size, entry count and name-length ceilings stop decompression bombs.
Why is a password-protected archive refused?
The browser library cannot decrypt it, so the tool reports that plainly instead of extracting partial garbage.
