Free GZ to TGZ converter

Why convert GZ to TGZ?

People convert GZ to TGZ because a .gz holds exactly one compressed file and cannot carry a folder, while a .tar.gz is the standard way to ship a folder on Linux and macOS.

How to convert GZ to TGZ

1. Choose your GZ file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .tgz. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .gz file?

Gzip compresses a single file — it does not bundle several. That is why it is nearly always seen wrapping a TAR archive as .tar.gz, and why it is the compression the whole web uses when serving pages.

What is a .tgz file?

A TGZ is a TAR archive that has then been gzipped: the bundling and the compression done by two separate tools, as Unix prefers. It is the standard distribution format for source code and Linux packages.

What to expect from this conversion

The conversion runs entirely in your browser and the file never leaves your device.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your GZ file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about GZ to TGZ

Is this GZ to TGZ converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my GZ file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

The conversion runs entirely in your browser and the file never leaves your device.

How do I convert GZ to TGZ on Windows, Mac or Linux?

The same way on all three: open this page in Chrome, Edge, Firefox or Safari, drop the GZ file, press Convert and download the TGZ. Nothing is installed and no admin permission is needed.

Can I convert several GZ files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Should I keep the original GZ file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that a .gz holds exactly one compressed file and cannot carry a folder.
