The application compresses a bunch of web files into an archive and allows you to browse them

CHReader is an application that lets you compress a group of related web files to an archive and browse it with a web browser. The archive will not be decompressed (it acts like a dedicated web server on port 8078 of your machine).

This way you can retrieve very large sites with web spiders and keep them in an optimal space-saving way always ready to be browsed.
