Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.

It can be especially useful for cases where:
•you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.)
•you need to work on a system that doesn’t have an OS installed
•you need to flash a BIOS or other firmware from DOS
•you want to run a low-level utility
Despite its small size, Rufus provides everything you need!

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.
