What is a HTML Minifier & Compressor?

An HTML minifier removes unnecessary whitespace, comments, and redundant characters from HTML markup to produce the smallest valid HTML file possible. Smaller HTML files load faster because there are fewer bytes for the browser to download, parse, and render. HTML minification is a standard step in modern web development build pipelines for exactly this reason. The HTML Minifier strips all inter-tag whitespace that does not affect rendering, removes HTML comments entirely, collapses multiple consecutive spaces into single spaces where safe to do so, and removes optional closing tags where the HTML5 specification permits their omission. The result is a compact HTML document that browsers render identically to the original while being significantly smaller on disk and over the network. All processing happens locally in your browser — nothing is transmitted to any external server.
