OpenAnyFile
Works
Viewing, inspecting and verifying. You get the contained stream, and if it is a tar it opens as a browsable archive tree. File details, exact byte size and the detected signature are always shown.
How to open a .tgz file
A TGZ file is a Gzipped Tar Archive, introduced by Unix community in 1992. Below: what is actually inside one, and how to open it without installing special software.
What is a .tgz file?
Gzipped Tar Archive is an archive format developed by Unix community, first appearing in 1992. It is normally produced by Source distributions, backups.
The DOS-friendly spelling of .tar.gz. Because tar bundles first and gzip compresses second, extraction is sequential — you cannot pull one file without streaming through what precedes it.

Open a .tgz file in your browser
OpenAnyFile routes .tgz to its gzip decompressor, which decompresses the contained stream, and if it is a tar it opens as a browsable archive tree.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .tgz file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the gzip decompressor.
- Your TGZ opens on its own viewer page: the contained stream, and if it is a tar it opens as a browsable archive tree.
- Use fullscreen for a closer look, or download the file back out unchanged. Works the same on Windows, macOS, Linux, Android and iOS, because it is just a web page.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Your {ext} file stays on your device
The entire pipeline — detection, decoding, rendering — runs client-side. Your browser hands the bytes to a decoder compiled to WebAssembly, the result is drawn to the page, and that is the whole journey. No account is created, no file is stored, and no analytics event carries your filename. This is also why there is no size limit imposed by a server: the only ceiling is your own available memory.
Frequently asked questions about TGZ files
Can I open a .tgz file without installing special software?
Yes. OpenAnyFile's gzip decompressor runs in your browser, so you can read a TGZ file with nothing installed. You get the contained stream, and if it is a tar it opens as a browsable archive tree. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a TGZ file?
Look at the first bytes rather than the extension. A genuine TGZ begins with 1F 8B 08. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .tgz by mistake is easy to spot.
Is it safe to open a TGZ file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .tgz file, exactly?
Gzipped Tar Archive — an application/gzip format created by Unix community since 1992. The DOS-friendly spelling of .tar.gz. Because tar bundles first and gzip compresses second, extraction is sequential — you cannot pull one file without streaming through what precedes it.
Does the same viewer handle formats related to TGZ?
Yes — the same engine also opens .gz, .001, .7z, so you can compare related files without switching tools.

These open with the same engine, so if you have one of these sitting next to your .tgz file, it will open too:
