What This Tool Does

GZIP compresses a single data stream, often the contents of one file such as a log, backup or download. This tool decompresses the .gz stream and places the recovered data into a standard ZIP archive, so you end up with a package that every operating system can open natively.

When the compressed stream is itself a TAR archive the tool detects that and packs the TAR contents into the ZIP instead, preserving the folder structure. Either way, the output is a validated ZIP file.

How It Works

The .gz file is opened and deflated using zlib, the same library used by GZIP itself. The recovered data is inspected: if it is a single file it is stored in the ZIP under its original name, and if it is a TAR archive the TAR entries are extracted and repackaged as ZIP entries.

Compatibility

  • Input: a GZIP-compressed stream (.gz, .tgz).
  • Output: a standard ZIP archive (.zip) with the decompressed contents.
  • TAR payloads inside .gz files keep their folder layout in the output ZIP.

Troubleshooting

  • A file that does not decompress as GZIP is reported honestly as invalid input.
  • Corrupted .gz data will stop at the point of damage rather than producing a fake output.
  • Very large .gz streams take longer; stay on the page until the download appears.

Frequently Asked Questions

What is the difference between .gz and .tar.gz?
A .gz is a single compressed stream. A .tar.gz is that stream applied to a TAR archive. This tool handles both: the TAR case keeps the folders.
Will the output open anywhere?
Yes, the result is a standard ZIP readable by all major operating systems.
Is anything compressed twice?
No, the data is decompressed once and then stored in the ZIP with normal ZIP compression.
Can I convert .gz to TAR too?
Yes, we offer a separate GZ to TAR converter on this site.
Does this tool support .tgz files?
A .tgz is simply a .tar.gz. Upload the .gz stream and the TAR payload will be preserved as folders in the ZIP.
