rar vs zip vs 7z : rpcmasterrace

7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as archives.

7Z provides best compression result with medium compression level (default on 7-Zip), and third best result with fast compression level (default on PeaZip), ...

At only a fraction of the speed of 7z, you will get max. ~30% compression, while there is no way to get up to ~55% compression with ZIP at all.

For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip. Strong AES-256 encryption in 7z ...

7-Zip compresses to 7z format 30–70% better than to zip format, and 7-Zip compresses to zip format 2–10% better than most other zip-compatible programs.

Compression Algorithms: The 7z format typically uses the LZMA (Lempel-Ziv-Markov chain algorithm) for compression, which provides better compression ratios compared to the standard Deflate algorithm used by ZIP . This results in smaller archive sizes

The main features of 7-Zip · High compression ratio in 7z format with LZMA and LZMA2 compression · Supported formats: · For ZIP and GZIP formats, 7-Zip provides a ... Download · Technical Support for 7-Zip · 7z Format · FAQs

A zip file is the conventional ZIP compression format while the 7-zip format is made by 7zip and is supposedly better and more efficient than ...

7zip/LZMA2 is faster that RAR but both of them are a lot slower than zip/deflate (about 2-3x or more, depends on settings).

7-Zip compresses to 7z format 30–70% better than to zip format, and 7-Zip compresses to zip format 2–10% better than most other zip-compatible programs.
