Frequently asked questions
Is my GZ file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a GZ file without installing software?
Drop the .gz file on this page. It opens straight away in the ZIP & Archive Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my GZ file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a GZ file, you'll see an error or can switch to the hex view to look at the raw bytes.
