How to open a 7z file online
The .7z format comes from 7-Zip and is popular because its LZMA compression packs files smaller than ZIP. The catch is that most systems cannot open a 7z file out of the box, especially macOS, where you would otherwise need to install a separate app.
This extractor runs 7-Zip decompression in your browser through a WebAssembly build of libarchive. Drop your .7z file above, enter a password if the archive is encrypted, and download the extracted files. It works identically on Windows, macOS, Linux, and mobile, and nothing is uploaded.
Compression methods and encryption
Archives created with the standard LZMA and LZMA2 methods extract here, which covers the vast majority of .7z files you will encounter. Extraction is one-way: this tool does not create 7z archives, so use the ZIP or TAR.GZ tools if you need to package files.
Encrypted 7z archives are supported. Because 7z can encrypt both file contents and the list of file names, you may be asked for the password before the contents can even be listed. That password is only ever used locally in your browser.
Frequently asked questions
How do I open a 7z file without installing 7-Zip?
Drop the .7z file into the tool above. It extracts in your browser using WebAssembly, so no 7-Zip install is needed. This is especially handy on macOS, which cannot open 7z files natively.
Can I create 7z archives?
No. This tool supports 7z extraction only. To create archives, use ZIP or TAR.GZ instead.
Are my files uploaded to a server?
No. 7z extraction happens entirely in your browser using WebAssembly. Your files never leave your device.
Does this support password-protected 7z files?
Yes. If the 7z archive is encrypted, you will be prompted to enter the password. Your password is processed locally.
What compression methods are supported?
LZMA, LZMA2, and other standard 7z compression methods are supported via the libarchive extraction engine.
Can I extract a 7z file on a Mac?
Yes. Because extraction runs in the browser, it works on macOS, Windows, Linux, and mobile without any extra software.
