Free GZ to ZIP converter

Why convert GZ to ZIP?

People convert GZ to ZIP because a .gz holds exactly one compressed file and cannot carry a folder, while a ZIP opens with a double-click on Windows, macOS and every phone.

How to convert GZ to ZIP

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 .zip. 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 .zip file?

ZIP bundles many files into one and compresses them, and every operating system has opened one natively for decades. It is the default way to send a folder to another person, and the container hiding inside DOCX, XLSX, EPUB and countless other formats.

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 ZIP

Is this GZ to ZIP 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.

Can I convert GZ to ZIP online without downloading software?

Yes. This is an online GZ to ZIP converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

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

How do I convert GZ to ZIP 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 ZIP. 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.

Can I convert GZ to ZIP without the command line or a script?

Yes — that is what this page is for. the command line does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

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.
