: The format supports military-grade AES-256 encryption . Unlike standard ZIP files, 7z allows users to encrypt file names, preventing unauthorized parties from seeing what files are inside the archive without a password.
: The format utilizes the advanced Lempel-Ziv-Markov chain algorithm (LZMA) as its default compression method. This allows it to pack files 30% to 70% tighter than traditional ZIP archives.
