What is File Compression Software?

File compression software reduces file sizes and bundles multiple files into single archives for efficient storage and transfer. These tools use algorithms like DEFLATE, LZMA, Brotli, and Zstandard to compress data, achieving 50-90% size reduction depending on file types. They create archive formats including ZIP, 7z, RAR, TAR, and GZ with options for encryption, password protection, and split archives for large files. Modern compression tools integrate with cloud storage, email clients, and file managers for seamless workflows. They handle batch compression, scheduled backup archives, and archive management. Enterprise use cases include backup compression, log file archiving, software distribution packaging, and secure file transfer with encrypted archives.
