HTTrack is a free (GPL, libre/free software) and easy-to-use offline
browser utility.
It allows you to download a World Wide Web site from the Internet to a
local directory, building recursively all directories, getting HTML,
images, and other files from the server to your computer. HTTrack
arranges the original site's relative link-structure. Simply open a
page of the "mirrored" website in your browser, and you can browse the
site from link to link, as if you were viewing it online. HTTrack can
also update an existing mirrored site, and resume interrupted
downloads. HTTrack is fully configurable, and has an integrated help
system.
