How to use the HTML Minifier

Paste any HTML and click Minify. The tool removes unnecessary whitespace, comments, and optional tags to reduce file size. All processing happens in your browser — nothing is sent to any server.

Why minify HTML for SEO?

Smaller HTML files load faster, and page speed is a confirmed Google ranking factor. Every kilobyte removed from your HTML improves Time to First Byte (TTFB) and Largest Contentful Paint (LCP), both part of Core Web Vitals.

FAQ

Does minification break HTML?No. Only non-essential whitespace and comments are removed. The HTML remains functionally identical.
