The choice between downloading a tar.gz (or .tar.gz) file and a ZIP file depends on several factors, including your operating system, the content of the file, and your specific needs. Here's a breakdown:
-
Compression Algorithm:
- Tar.gz: Uses the gzip compression algorithm along with tar archiving. It's commonly used in Unix-like operating systems such as Linux.
- ZIP: Uses the ZIP compression algorithm. It's more widely supported across different operating systems, including Windows, macOS, and Unix-like systems.
-
File System Compatibility:
- Tar.gz: Preserves Unix file permissions and ownership when extracted on Unix-like systems. It doesn't inherently support Windows file systems and might require additional tools or software to extract properly on Windows.
- ZIP: Works seamlessly across different operating systems. Preserves file permissions on Unix-like systems but may not be as robust in doing so as tar.gz.
-
Compression Ratio:
- Tar.gz: Generally offers better compression ratios, making it more efficient in terms of file size.
- ZIP: Offers decent compression ratios but may not always be as efficient as tar.gz.
-
Ease of Use:
- Tar.gz: Often used by experienced users on Unix-like systems due to its familiarity and efficiency.
- ZIP: More user-friendly for general purposes, especially on Windows systems, where it's natively supported.
-
Community and Ecosystem:
- Tar.gz: Widely used in Unix-like communities and ecosystems. It's the standard for distributing source code, software packages, and archives in the Linux world.
- ZIP: More commonly used in general-purpose file archiving and distribution, especially in contexts where cross-platform compatibility is important.
In summary, if you're working primarily within a Unix-like environment and need efficient compression with preservation of file permissions, tar.gz is often the preferred choice. However, if you require cross-platform compatibility or are working in a Windows environment, ZIP may be more suitable. Ultimately, both formats have their advantages and are widely used in different contexts.
TLDR;
| Aspect | Tar.gz | ZIP |
|---|---|---|
| Compression Algorithm | gzip + tar | ZIP |
| File System Compatibility | Preserves Unix file permissions and ownership. May need extra tools for Windows. | Works seamlessly across different OS. |
| Compression Ratio | Generally offers better compression ratios. | Offers decent compression ratios. |
| Ease of Use | Often used in Unix-like environments by experienced users. | More user-friendly, especially on Windows. |
| Community/Ecosystem | Widely used in Unix-like communities and ecosystems. | Commonly used in general-purpose archiving and distribution. |
Each of these factors contributes to the suitability of the respective format based on specific needs and contexts.

I recently implemented a function to export zip files, but I chose this format because it was requested, I didn't consider whether another format could be the best choice.
I will consider these points next time, thanks for sharing 😀
The smallest choice can increase or decrease productivity. Thank you for your time on reading this.
Another important distinction is that the zip format is indexed by default, so it is very fast to extract a single file, making it very useful for large collections of files.
With tar you are free to choose what compression you use, depending on your own trade of speed vs. size.
