A .gz file from a server, a log rotation or a download has to be opened on a machine with no gzip tooling.

What actually changes
GZ and ZIP are not the same picture in two wrappers.
The gzip stream is decompressed and the resulting single file is stored in a ZIP archive, which Windows Explorer opens natively.
Worth knowing first
Gzip compresses exactly one stream and holds no directory. A .tar.gz is therefore two layers, and converting only the outer one leaves a TAR inside the ZIP that Windows users then have to unpack again. Convert both layers or say which you did.
Questions
GZ to ZIP, answered
Why is there no folder structure in my .gz?
There never was. Gzip compresses a single stream, and the folder structure lives in the TAR inside it.
Does the compression get worse?
Marginally. Both use Deflate, so the difference is container overhead rather than algorithm.
