About the online 7z extractor
This online 7z extractor lets you open 7z archives right in your browser — no need to install 7-Zip or any other software. ZIP, RAR (v4 and v5), tar, tar.gz and other archive formats are also supported.
All processing happens locally on your device using JavaScript and WebAssembly — nothing is sent to a server. This makes it safe for personal documents, work archives and confidential data.
Drop a 7z file into the upload area to see the list of files inside. Download individual files or click «Download all» to get everything packed into a new ZIP. Works on Windows, macOS, Android and iOS.
Frequently asked questions about the online 7z extractor
How do I extract a 7z file online for free?
Drop your 7z file into the upload area. The tool shows the list of files inside. Click «Download» next to any file or «Download all» to get everything in one ZIP. Free, no sign-up required.
Can I open a 7z file without installing 7-Zip?
Yes. The extractor works right in the browser — no 7-Zip installation needed. Just drop the 7z file on the page and download the contents.
Are my files uploaded to a server?
No. Extraction runs entirely in your browser with JavaScript. Files never leave your device.
Which other formats are supported?
Besides 7z, the tool opens ZIP, RAR (v4 and v5), tar, tar.gz (tgz), tar.bz2, tar.xz and other popular archive formats.
Why won't my 7z archive open?
Check that the file is not corrupted and has a .7z extension. Multi-volume 7z archives (.7z.001, .7z.002…) are not supported — upload a single complete archive file.
