The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.
View the web archive through the Wayback Machine.
Content crawled via the Wayback Machine Live Proxy mostly by the Save Page Now feature on web.archive.org.
Liveweb proxy is a component of Internet Archive’s wayback machine project. The liveweb proxy captures the content of a web page in real time, archives it into a ARC or WARC file and returns the ARC/WARC record back to the wayback machine to process. The recorded ARC/WARC file becomes part of the wayback machine in due course of time.

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.
