What does GZ Converter do?

The GZIP (.gz) format works on the principle of “single file“. Therefore, conversion should always be considered in two stages:

  1. Decompress: GZ is decompressed, resulting in a single output file.
  2. Repack: This output file is repackaged according to the target format (ZIP/7Z/RAR/TAR/TAR.GZ/TAR.BZ2).

Frequently Asked Questions

Is this tool free?
Yes, the GZ Converter is completely free.
Are my files stored on the server?
No, your files are only used during the process and are deleted afterwards.
Is there a limit on usage?
Yes, there is a maximum file size limit of 100 MB.
Which formats are supported?
You can convert GZ files to 7Z, RAR, TAR, TAR.BZ2, TAR.GZ, and ZIP formats.
Does it work on mobile?
Yes, the tool is accessible and usable on mobile devices as well.

The part that determines quality here is the “smart tarball detection”:

  • If the output file when GZ is decompressed is .tar, this is actually the “tar.gz” scenario. To prevent the complaint of “only single file output”, the tool should offer these two modes:
    • Simple mode: places the resulting .tar file into the target archive
    • Content mode: extracts the .tar content > transfers it to the target archive with folder structure. This automatically resolves the confusion of “what is tar.gz / what is tgz / what is a tarball”.

Supported conversions

  • GZ to 7Z
  • GZ to RAR
  • GZ to TAR
  • GZ to TAR.BZ2
  • GZ to TAR.GZ
  • GZ to ZIP

When to choose which output?

  • ZIP: Most extensive compatibility. The goal is “let everyone open it”.
  • 7Z: Archive standardization (single type archive).
  • RAR: If the institution/agency has a standard (RAR production may depend on your infrastructure; if not supported, disable it).
  • TAR: Packaging (no compression). Intermediate format in Linux/DevOps workflows.
  • TAR.GZ: Classic tarball standard; natural output of scenarios like “extract tar.gz”.
  • TAR.BZ2: tar + bzip2; smaller in some content, generally slower.

Interface flow (single interface)

  1. Upload GZ
  2. The system analyzes:
  • GZIP integrity (CRC vs) and decompression success (corrupted gz warnings)
  • Decompressed output name/extension
  • “Is the output TAR?” (tarball detection)
  1. Select target format
  2. Settings:
  • TAR mode: simple / content (only if the decompressed output is TAR)
  • compression level (fast/balanced/maximum)
  • “keep original” option (gzip keep original / gunzip keep original behavior; practically “-c” logic)
  • output name standard
  1. Convert > download

Error messages

  • Corrupted GZ: “File is damaged or missing. GZIP decompression could not be completed.”
  • TAR detection: “This file may be a tarball (tar.gz). If you choose content mode, the folder structure will be preserved.”
  • RAR not supported: “RAR output is not supported on this system. Choose ZIP or 7Z.”
  • Output could not be generated: “Output could not be generated for the selected format > try ZIP or TAR.GZ.”
