This tool uses WebAssembly (the libarchive engine) to read tar.gz archives directly in your browser. There is no server: your file is processed locally and never uploaded. That makes it safe for source code, backups, and private datasets.
Got a different archive? Use Open RAR Online for .rar or Open 7z Online for .7z. Need to make an archive instead? Use the ZIP Creator. For a full walkthrough, read How to Open tar.gz Files (Windows, Mac & Online).
A .tar.gz combines two steps: tar bundles many files and folders into a single archive, and gzip compresses that bundle. It is the default packaging format across Linux, open-source projects, and server tooling, which is why you most often meet it when downloading source code, software releases, or backups.
Are my files uploaded to a server?
No. Everything happens 100% in your browser using WebAssembly (libarchive). Your archive never leaves your device and is never uploaded to any server.
What is a tar.gz file?
A .tar.gz (also seen as .tgz) is two formats combined: tar bundles many files into one, and gzip compresses that bundle. It is the standard archive format in the Linux and developer world, used for source code, software releases, server backups and datasets.
Why is tar.gz hard to open on Windows?
Older Windows versions had no built-in support for tar.gz, so double-clicking did nothing. Windows 11 added command-line tar support, but there is still no simple right-click extract and no easy way to peek inside without fully extracting. This browser tool opens and previews tar.gz instantly with no install.
Can macOS open tar.gz natively?
Yes, macOS Archive Utility extracts tar.gz when you double-click it. This tool is still useful on a Mac when you want to view the contents and download just one file without unpacking the whole archive, or when you are on a borrowed or restricted machine.
Which formats does it support?
It opens .tar.gz, .tgz, .tar, .gz, .tar.bz2 and .tar.xz archives. For .rar files use our Open RAR tool, and for .7z files use our Open 7z tool.
Is there a file size limit?
The free plan supports archives up to 200 MB. For larger archives, a one-time 24-hour Day Pass ($2.99) removes the limit instantly.
Is it free?
Yes. Opening and extracting tar.gz archives up to 200 MB is completely free, with no signup.
