Key differences between the two formats
| Feature | TAR.GZ | 7-Zip |
|---|---|---|
| Compression algorithm | gzip (DEFLATE) | LZMA2 |
| Compression ratio | Good | Excellent (best-in-class) |
| Encryption | None | AES-256 |
| Platform | Native Unix/Linux | Cross-platform |
| Solid archives | No | Yes |
| Open standard | Yes | Yes |
| Best for | Linux/Unix distribution | Maximum compression, cross-platform |
When to Convert
Common scenarios where this conversion is useful
Maximizing compression ratio
7-Zip's LZMA2 algorithm consistently achieves better compression than gzip. Convert large TAR.GZ archives to 7z to save additional storage space.
Adding archive encryption
Convert TAR.GZ archives to 7-Zip to add AES-256 encryption for secure storage and sharing of sensitive files. TAR.GZ offers no native encryption.
Cross-platform sharing
7-Zip is natively supported on Windows (built-in), macOS, and Linux. Convert TAR.GZ files for sharing with Windows users who may not have TAR tools installed.
Long-term archival storage
Use 7-Zip's superior compression for archiving large TAR.GZ backups that need to remain accessible but take up minimal storage space over time.

2
Server extracts and repacks as 7z
Our server uses 7-Zip to decompress the TAR.GZ and repack the contents as a .7z archive with LZMA2 compression for maximum size reduction.
-
3
Download your 7z file
Download the .7z archive. Your original TAR.GZ and the output file are automatically deleted from our servers after conversion.
Frequently Asked Questions
7-Zip typically achieves 15-30% better compression than gzip. It also supports AES-256 encryption and solid archive mode, which TAR.GZ does not.
Yes. Files are uploaded over HTTPS and automatically deleted from our servers immediately after the conversion is complete.
Yes. All files, directories, and filenames from the TAR.GZ archive are preserved in the resulting 7-Zip archive.
Yes. The free 7-Zip app is available for macOS. Alternatively, tools like The Unarchiver support .7z files natively on macOS.
Yes. Install p7zip-full on Ubuntu/Debian (sudo apt install p7zip-full) or p7zip on RPM-based systems, then use the 7z command.
The conversion API supports files up to 50MB. For very large archives, consider splitting them first or using command-line 7-Zip directly.
The converter produces an unencrypted 7z archive. To add AES-256 encryption to the output, use a local 7-Zip installation and set a password after converting.
Yes. ChangeThisFile provides this conversion for free, with no account required and no limits beyond the 50MB file size cap.
7-Zip (LZMA2) typically achieves the best compression ratios of all common archive formats, outperforming ZIP, TAR.GZ, TAR.BZ2, and RAR in most benchmarks.
