More about the HTML Minifier
Stripping whitespace and comments is the easy, safe part of minifying HTML; going further by dropping optional closing tags, HTML5 doesn't actually require a closing </li> or </p> tag in plenty of contexts, is a more aggressive technique that shaves off more bytes but genuinely requires understanding exactly which tags are safe to omit without breaking the page's structure. This tool minifies HTML by removing whitespace and comments, and optionally dropping those legitimately optional tags for a more aggressive size reduction, rather than only handling the safest, most conservative whitespace stripping. Useful for shaving extra load time off a page by removing whitespace and comments before it ships, going further with optional tag removal when every byte of page weight matters, or minifying a large HTML file without introducing a rendering bug from an unsafe optimization.
