How to convert GZ to ZIP

Plain .gz holds one file; .tar.gz (also written .tgz) bundles many files inside a .tar - both layers must be extracted before repacking as ZIP.
No data is altered: both GZIP and ZIP use lossless DEFLATE compression, so the files inside are byte-identical to the originals.
The output .zip may be slightly larger than the source .gz, and Unix file permissions stored in .tar archives are not preserved in ZIP.

Do I need extra software to open a GZ file on Windows?

Yes - Windows cannot open .gz files natively, so install 7-Zip or PeaZip (both free) to extract and repack.

Will the files inside be identical after converting?

Yes. Both formats use lossless DEFLATE compression, so no data is changed or lost during the process.

Can I convert `.tar.gz` to ZIP in one step?

Tools like PeaZip and Keka extract the full .tar.gz in one click; adding the output to a .zip is a quick second action.

Why might the new ZIP be larger than the original GZ?

ZIP compresses each file individually, which is slightly less efficient than gzip applied to the entire archive as a single stream.
