JPEG-2000 and another wavelet-based codec MrSID https://en.wikipedia.org/wiki/MrSID https://en.wikipedia.org/wiki/MrSID are used for archival storage of high-resolution scans, e.g. by the Library of Congress http://memory.loc.gov/ammem/help/compression.html http://memory.loc.gov/ammem/help/compression.html JPEG has the big advantages that it is built in to web browsers, can be decoded effectively on less powerful hardware, and is “good enough” for most typical uses.
