The official history of 7-Zip documents decades of refinements:

: It allows for any compression, conversion, or encryption method to be used. Russo History.7z

: It utilizes AES-256 encryption for both data and the archive's header (filenames).

: In many benchmarks, 7z can compress files 30–70% better than the standard ZIP format. Expanded support for macOS formats, including archives using

7-Zip was first released in by Russian developer Igor Pavlov . The project was designed as a high-compression alternative to established formats like ZIP and RAR. The core of its efficiency lies in the LZMA (Lempel-Ziv-Markov chain algorithm) and LZMA2 compression methods, which often achieve significantly smaller file sizes than standard ZIP files.
