ZIP is the universal archive format with per-file DEFLATE compression and random access capability, supported by every operating system. GZ (Gzip) is the standard Unix single-file compression format, also using DEFLATE but applied as a stream compressor rather than an archive format. GZ is the backbone of web content-encoding, Unix log compression, and package distribution.
Converting ZIP to GZ extracts the archive contents and produces gzip-compressed output. For single-file ZIP archives, this produces a streamlined .gz file. For multi-file ZIP archives, the output is a .tar.gz tarball that preserves the directory structure. This conversion integrates ZIP-distributed content into Unix-native workflows.
Unix system administration, web infrastructure, and DevOps tooling are built around gzip. HTTP content-encoding uses gzip by default. Log rotation produces .gz files. Package managers distribute .tar.gz tarballs. When you receive files in ZIP format that need to enter these Unix-native workflows, converting to GZ (or .tar.gz) aligns the format with the ecosystem's expectations.
For single-file archives, .gz is a more efficient container than ZIP. ZIP adds per-file headers, a central directory, and end-of-central-directory records — overhead that a simple .gz file avoids. A single file compressed as .gz is 100-500 bytes smaller than the same file in a ZIP, with identical compression since both use DEFLATE.
The ZIP central directory is parsed to enumerate entries. Each file is decompressed from its individual DEFLATE stream and CRC32-verified. For single-file ZIP archives, the extracted file is gzip-compressed directly to produce a .gz output. For multi-file ZIP archives, extracted files are bundled into a tar archive preserving the directory hierarchy, then the tar is gzip-compressed to produce a .tar.gz output. Both ZIP and GZ use DEFLATE, so compression ratios are nearly identical.
Completely lossless for file content. Every file is extracted from ZIP (CRC32-verified) and recompressed with gzip. File data is byte-for-byte identical. Both formats use DEFLATE, so the output is approximately the same size as the input. ZIP-specific features (per-file random access, central directory) are replaced by gzip's simpler sequential format.

ZIP to GZ converts the universal archive format into Unix's native compression format. Single-file ZIPs become streamlined .gz files; multi-file ZIPs become standard .tar.gz tarballs.
