FLIF (Free Lossless Image Format) is a compressed image file format. Images can be compressed losslessly or lossy.
It uses a compression algorithm called MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding), which is a form of arithmetic coding.

History
FLIF was first announced in 2015, and the first stable version (named FLIF16) was released in 2016. Note that FLIF files or software created before about 2016-08 are likely to be incompatible with the current FLIF format. The creator, Jon Sneyers, later created another graphic format, FUIF, designed for responsive web design.
Identification
FLIF files begin with ASCII "FLIF".
The byte at offset 4 is one of the characters from the ASCII string "134ACDQSTacd".
The byte at offset 5 is one of the characters from the ASCII string "012".
