Extract 7Z FAQ
What is a 7z file?
A high-compression format created by the 7-Zip program. It compresses well, but Macs and phones usually cannot open it out of the box. This page extracts it with nothing to install.
How do I open 7z on Mac?
macOS Archive Utility does not support 7z. Just drop the file onto this page and it extracts right in your browser.
Are password-protected 7z files supported?
Yes. A password field appears when the archive is encrypted. Your password never leaves the browser.
Is it safe?
Extraction happens entirely inside your browser (WebAssembly), so files never travel over the network. Once the page is loaded, it even works offline.
