ZIP is the most universally supported archive format, created by Phil Katz in 1989. Unlike TAR, ZIP combines archiving and compression in one format, with each file compressed individually using Deflate. This allows extraction of single files without decompressing the entire archive. ZIP has been natively supported by Windows since XP (2001), macOS, and all Linux distributions.

ZIP's universal compatibility makes it the default choice for software distribution, email attachments, and cross-platform file sharing. While 7z and RAR achieve better compression ratios, ZIP requires no additional software on any modern operating system. The format supports AES-256 encryption, large files over 4GB (ZIP64), and stores file metadata including timestamps and permissions.
ISO (ISO 9660) is a disc image format originally designed for CD-ROMs. The format creates an exact sector-by-sector copy of an optical disc, including the filesystem structure. Modern ISO files use Joliet extensions for long filenames and Unicode support. ISO is uncompressed, prioritizing compatibility and direct mounting over file size.

ISO's killer feature is double-click mounting: Windows 10+, macOS, and Linux can mount ISO files as virtual drives without any software. This makes ISO ideal for software distribution-users double-click to mount, browse files like a folder, and run installers directly. No extraction step, no temporary files, no cleanup needed.
