What Is ZIP?
ZIP is the most widely used archive format. It compresses one or more files into a single container, reducing total file size and simplifying file transfer. ZIP is natively supported by Windows, macOS, and Linux.
- File compression and bundling
- Email attachments
- Software distribution
- Backup archives
ZIP uses DEFLATE compression by default. Conversion between archive formats re-packages the contents without altering the files inside.
What Is GZ?
GZ (gzip) is a compression format that uses the DEFLATE algorithm. It is commonly used in Unix and Linux environments, often combined with TAR to create compressed archive files (.tar.gz). Gzip provides good compression ratios.
- Compressing TAR archives
- Web server content compression
- Log file compression
- Data transfer optimization
GZ compresses a single file or data stream. For archiving multiple files with gzip compression, the files are first combined with TAR and then compressed with gzip.
