-'''WARC''' is an archive file format which has been the predominant format for [[Web]] ([[HTTP]]) archives from 2009 to (as of 2019) the present; it is also used for archives of documents collected through other prococols (e.g. [[FTP]]), and could technically be used to store a collection of ordinary files. It is the successor to the [[ARC (Internet Archive)|ARC]] format. It was developed under the auspices of the [http://netpreserve.org/ International Internet Preservation Consortium], and standardized as ISO 28500:2009, Information and documentation -- WARC file format.  WARC was developed as an extension to ARC in part to provide better capabilities for managing Web archives for the long term, allowing for capture of more metadata about the circumstances of archiving.

There are currently (2019) two versions of WARC: 1.0 and 1.1, formally ISO 28500:2007 and ISO 28500:2017, respectively.
 WARC files are often compressed using [[gzip]], resulting in a '''.warc.gz''' extension. In cases where the warc.gz file needs to randomly accessed (namely, as part of web archives accessible page-by-page), this will consist of one gzip stream for each WARC record, concatenated together (which makes for a valid gzip file). This allows any single record to be accessed by an offset, and (when the entire file is decompressed) also preserves the original WARC.
-There is also a specification for a [[Web Archive Metadata File]]. Another metadata format used with WARC files is [[CDX]].
