Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about FLIF?
Summarize this article for a 10 year old
Free Lossless Image Format (FLIF) is a lossless image format claiming to outperform PNG, lossless WebP, lossless BPG and lossless JPEG 2000 in terms of compression ratio on a variety of inputs.[4]

FLIF supports a form of progressive interlacing (a generalization of the Adam7 algorithm) with which any partial download (greater than couple hundred bytes[5]) of an image file can be used as a lossy encoding of the entire image.
Jon Sneyers, one of the developers of FLIF, since combined it with ideas from various lossy compression formats to create a successor called Free Universal Image Format [Wikidata] (FUIF), which itself was combined with Google's PIK format to create JPEG XL. As a consequence, FLIF is no longer being developed.[1]
