Why Minify HTML?
Minification removes all characters from HTML source that are unnecessary for browsers to render the page — spaces, newlines, comments, and redundant attributes. This reduces the file size transferred over the network, resulting in faster page loads and better Core Web Vitals scores.
How Much Does HTML Minification Help?
Typical HTML minification saves 5–20% of file size on its own. Combined with GZIP compression on the server (which most web hosts enable by default), total transfer savings can reach 70–80% compared to raw, uncompressed HTML.
Will minification break my HTML?
No — whitespace inside
<pre>, <textarea>, and similar elements is preserved. Only cosmetic whitespace between tags is removed.Should I minify HTML in production?
Yes — most build tools (Webpack, Vite, Gulp) minify HTML automatically. For static sites, you can pre-minify the output files.
Does it minify inline CSS and JS?
Enable the "Minify inline CSS" and "Minify inline JS" options to compress code inside
<style> and <script> tags as well.Is the output valid HTML?
Yes — the minifier produces standards-compliant HTML5. It does not alter tag structure, only presentation-level whitespace.
