What is a TGZ file?
TGZ stands for Gzip-compressed tar archive. It was created by the GNU project and first released in 1992. TGZ is short for .tar.gz: a TAR bundle compressed as a whole with gzip. It is the standard way Linux and open-source projects distribute source code.
TAR.GZ is the same format under another extension.
| Type | archive |
|---|---|
| Compression | Lossless |
| In a browser | opens natively on macOS and Linux, and with 7-Zip on Windows |
| Common uses | source code releases and Linux software |
| MIME type | application/gzip |
Which format should you convert TGZ to?
- TGZ to ZIP to open on any computer or phone without extra software.
- TGZ to TAR for Linux, Mac and server tools.
How to open a TGZ file
Whether a TGZ file opens with a double click depends on the device. Here is what works on each, without buying software:
| Windows | ZIP opens natively; Windows 11 opens RAR, 7Z and TAR too since 2023. 7-Zip handles everything on older versions. |
|---|---|
| Mac | Archive Utility opens ZIP and TAR; The Unarchiver opens RAR and 7Z. |
| iPhone and iPad | The Files app opens ZIP. Other formats need an app. |
| Android | Files by Google opens ZIP; ZArchiver opens most other formats. |
| Web browser | TGZ opens natively on macOS and Linux, and with 7-Zip on Windows. |

TGZ compared with other archive formats
How TGZ stacks up against the formats people most often convert it to or from:
| Format | Compression | Usually contains | Released | Best for |
|---|---|---|---|---|
| TGZ | Lossless | a TAR archive compressed with gzip | 1992 | source code releases and Linux software |
| ZIP | Lossless | many files and folders, each compressed separately | 1989 | sending several files at once and downloading software |
| RAR | Lossless | many files and folders, compressed as a whole | 1993 | large downloads split into parts and files shared on forums |
| 7Z | Lossless | files compressed with LZMA or LZMA2 | 1999 | maximum compression for backups and software distribution |
| TAR | Lossless | files and folders joined end to end, without compression | 1979 | software source code and Linux and Mac backups |

- Adjust the settings if you need to; the defaults suit most people.
- Press Convert and save each file with its Download button. Nothing is uploaded at any point.
Tips for converting TGZ files without losing anything
Converting a TGZ file is lossless: every file inside comes out byte for byte identical, and only the archive around them changes.
- ZIP is the safe choice for sharing, because every system opens it without extra software.
- Use 7Z or TAR.GZ for backups and large collections; 7-Zip on a computer creates them.
- Archives are lossless: converting between formats never changes the files inside.
- Keep the original until you have checked the new archive opens and holds everything.
- Give archives clear names with a date, such as project-2026-09.zip, so backups are easy to find later.
- Check free space first: extracting needs room for every file inside, which can be several times the archive size.
- Avoid nesting archives inside archives; one level is easier to open on every device.
Convert TGZ files from the command line
7-Zip extracts any of these formats, and a second command packs the result:
7z x input.tgz -oextracted
cd extracted && 7z a ../output.zip .The converter on this page does the same job in your browser, without installing anything.
