Questions

How do I convert GZ to 7Z?

Drop your GZ file on this page, or choose it. Anyfile converts it on your device in a moment and the 7Z downloads straight away. To change it first, open it in the archive opener.

Is my GZ file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several GZ files at once?

Yes. Drop them together and you get one ZIP with every 7Z inside.
