Google is your friend. A search for the terms extract and webarchive
turns up useful items in the first page of results.

> Is this format common and standard to all browsers?
No. While many browsers will save archived versions of web pages, they
all seem to have their own technique.
> And what is it similar to?
It's similar to the plist files that pervade a Mac OS X installation. As
similar as you can get, in fact.

Extract using WebArchive Folderizer and then recompress using whatever
format/tool you like.
