Free Lossless Image Format (FLIF) is a work-in-progress lossless image format based on MANIAC compression. FLIF claims to outperform PNG, FFV1, lossless WebP, lossless BPG and lossless JPEG 2000 in terms of compression ratio on a variety of Inputs.

FLIF supports a form of progressive interlacing (a generalization of the Adam7 algorithm), which means that any partial download of a compressed file can be used as a reasonable lossy encoding of the entire image.

The format was initially announced publicly in September 2015,[2] with the first alpha release occurring about a month later, in October 2015.[1]

For compression, FLIF uses MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding), a variant of CABAC where the contexts are nodes of decision trees which are dynamically learned at encode time.
