Format Details
ZIP
ZIP is the most widely used archive format, invented in 1989 by Phil Katz, that compresses and packages multiple files into a single container using the DEFLATE algorithm. It supports individual file compression with optional password protection and is natively supported on Windows, macOS, and Linux without additional software. ZIP is the universal standard for distributing files, software installers, and document packages due to its ubiquitous support.
7Z
7Z is a high-compression archive format associated with the free, open-source 7-Zip archiver. It uses the LZMA and LZMA2 compression algorithms to achieve significantly better compression ratios than ZIP and RAR, often reducing file sizes by 30-70% more than competing formats. 7Z supports AES-256 encryption, solid compression, multi-volume archives, and can handle files of virtually any size.
