How this works: this page loads libarchive, compiled to WebAssembly, and runs it in a background worker in your browser tab. Your archive file is read locally and is never sent to any server.
Troubleshooting
A password-protected RAR or 7-Zip archive won't extract
This page can list what's inside an encrypted archive, but extracting a password-protected archive isn't supported here yet. Use a desktop tool such as 7-Zip or WinRAR, which can prompt for the password.
Extraction seems to hang on a very large archive
The whole archive is decompressed inside your browser tab's memory. A multi-gigabyte archive can be slow, or exhaust the tab's available memory. For very large archives, a desktop tool like 7-Zip will generally be faster and more reliable.
Prefer the command line?
This page is powered by libarchive, the same open-source engine behind the 7-Zip and unrar command-line tools.
