It takes a HTML and reduces it to basic HTML tags, such as paragraphs, anchors, images, etc. It removes all CSS styling, scripts, non-basic tags like canvas or object etc. The result is simple and clean HTML.
==Use cases:==
* reusing old HTML, for example, when migrating a website.
* rewriting HTML supplied by someone else - removing their styling first and then implementing own styling
* Simplifying complex HTML generated by a tool.
