Question 1

How does 7z compare to ZIP and RAR?

Accepted Answer

7z typically compresses 30–70% better than ZIP and 5–15% better than RAR. However, 7z compression is slower. Decompression speed is comparable. 7z is open-source (LGPL), unlike RAR.

Question 2

Is 7z supported on all platforms?

Accepted Answer

7-Zip is available on Windows, Linux, and macOS. The format is open-source, so third-party tools (PeaZip, Keka, The Unarchiver) support it on all platforms. Most programming languages have 7z libraries.
