'''LZ5'''/'''Lizard''' is a compressed data format, and compressed file format.

The original name was LZ5. There were two major versions of LZ5: 1.x and 2.x. In 2017, LZ5 2.x was renamed to Lizard 1.x. (Or something like that. More research may be needed here.)

LZ5/Lizard was apparently developed by Przemyslaw Skibinski, based on [[LZ4]] source code by Yann Collet.

== Disambiguation ==
This "LZ5" is not related to the compression scheme identifiers used by [[LArc]] and [[PUT]].

== Identification ==
LZ5 1.x compressed files start with bytes {{magic|05 22 4D 18}}.

LZ5 2.x and Lizard 1.x compressed files start with {{magic|06 22 4D 18}}.

Compare to [[LZ4#Identification]].
