About the GZ to TGZ Converter
Need to turn a GZ file into TGZ? This free converter changes GZ archives into TGZ in a few seconds, right in your browser. People usually convert because Windows users and many apps expect ZIP files, while TGZ gives you a compressed .tar.gz archive. TGZ files open in Linux and macOS terminal, 7-Zip, WinRAR and Windows 10+ (tar.exe).
Archives are unpacked and repacked with fflate, a fast open-source compression library, entirely in your browser. Because everything happens on your own device, your archives are never uploaded, stored or seen by anyone else, which makes it safe for backups, source code and confidential files.
What to expect: file names and folders are preserved; encrypted (password-protected) archives cannot be opened.
How to use the GZ to TGZ Converter
- Click "Choose files" or drag your GZ archives onto the box. You can add several at once.
- Choose the compression level if the output is compressed.
- Press "Convert to TGZ". The conversion runs on your device and shows its progress.
- Download each TGZ file, or use "Download all (ZIP)" when you converted several.
- Open the result in Linux and macOS terminal or 7-Zip to check it; your original GZ is never changed.
Tips & benchmarks
- The whole archive is compressed at once, so many small text files shrink very well.
- Password-protected (encrypted) archives cannot be converted; extract them with the password first.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the TGZ to a website or government portal.

There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.

What is a GZ file?
Gzip was written in 1992 as a free replacement for the Unix compress program. It compresses a single file, which is why several files are first bundled with tar to create a .tar.gz.
What is a TGZ file?
A TGZ (or .tar.gz) is a TAR archive compressed with gzip. Compressing the whole bundle at once often makes it smaller than a ZIP of the same files, so Linux software and backups are usually shipped this way.
