Does 7z compress better than zip?

Indeed, many people have similar questions about Does 7z compress better than zip. I often package files, and here is a brief summary: Generally speaking, 7z has a much better compression rate than zip for plain text, source code, and office documents, which can be 20%-40% smaller. However, when it comes to compressed files such as pictures, videos, and compressed packages, the difference between 7z and zip is very small.

As for the compatibility issue, there is indeed a point. The Windows system can only decompress zip directly, and 7z requires additional software (such as 7-Zip, Keka, etc.), so if you want to share it with others or transfer it across devices, you have to consider its versatility. Overall, Does 7z compress better than zip? The answer is yes, but it depends on the specific scenario. It is very cost-effective to use 7z for your own storage, and zip is safer to send files to others.
