About the online GZ extractor
This online GZ extractor lets you open .gz and tar.gz files right in your browser — no need to install gunzip, 7-Zip or any other software. Both standalone .gz files and tar.gz (tgz) archives are supported. ZIP, RAR (v4 and v5), 7z, tar and other 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 logs, backups and confidential data.
Drop a GZ file into the upload area to see the contents. Download individual files or click «Download all» to get everything in one ZIP. Works on Windows, macOS, Linux, Android and iOS.
Frequently asked questions about the online GZ extractor
How do I extract a GZ file online for free?
Drop your .gz or tar.gz file into the upload area. The tool shows the contents. Click «Download» next to any file or «Download all». Free, no sign-up required.
What is the difference between .gz and .tar.gz?
A .gz file is a single compressed file (gzip). A .tar.gz file is a tar archive (multiple files) compressed with gzip. The tool handles both.
Are my files uploaded to a server?
No. Extraction runs entirely in your browser with JavaScript. Files never leave your device.
Can I open a GZ file on Windows without extra software?
Yes. The tool works in any browser on Windows, macOS, Linux, Android and iOS. No additional software needed.
Why won't my GZ file open?
Check that the file is not corrupted and has a .gz or .tar.gz (.tgz) extension. A renamed file with a non-standard extension may not be recognised.
