Stream compression formats

A stream format takes a stream of bytes, and outputs a different, hopefully smaller, stream of bytes. These compression formats are often used internally in other data structures to compress data, as well as in network protocols, such as http. Used stand-alone, a stream compression format does not offer archiving capability, however in the UNIX doctrine, an archiver like tar can be combined with an archive format to produce a proper compressed archive.

Compression algorithms and compressed data formats

(excluding formats usually used as file formats)

Graphics compression

See Graphics#Compression for compression formats used primarily with graphics.

Specific file formats/programs

(multi-file compressors are in Archiving)

Transparent file compression

(An obsolete technique in which a background process hooks into the OS and decompresses files transparently when they are read. Compression is usually done manually. The line between this and Disk compression can be blurry.)

Disk compression

(Transparent disk compression software and the like, excluding filesystem formats.)

For filesystem formats that feature compression, see Filesystem.

Executable compression

See Executable compression.
