Questions tagged [gzip]

GZip/gzip is both the name for a compressed data format and any of several software applications implementing this format. Use this tag for questions about implementing the library on your program.

gzip is the name for the compressed data format used by the eponymous GZip application for compressing and decompressing data.

The format is based on the deflate compressed data format, with the addition of a file metadata header and a CRC32 checksum. It is defined in RFC 1952. It is commonly used to compress HTTP requests and responses, and also often combined with the tar format for archival.

The most known standalone command-line implementation is GNU zip. The format is also implemented by the zlib library, and in this form used in many applications.
