HTML Minifier

It strips <!-- --> comments, collapses whitespace directly between tags (> < becomes ><), and squeezes tabs, newlines, and repeated spaces down to single spaces - all through regex replacements rather than a real HTML parser.

It is useful for trimming a static page or email template before shipping it, cutting out formatting whitespace that a browser render would not miss anyway.

Not always - the page itself warns that it is a basic whitespace/comment minifier, so it can misbehave on markup where whitespace is meaningful, such as inside <pre>, <textarea>, or inline scripts containing template literals. Check those sections manually after minifying.
