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.

[edit] 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.
[edit] 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".
