HTML Minifier

Minify HTML by removing whitespace, comments, and unnecessary characters.

HTML Minification

HTML minification removes comments, collapses whitespace, and strips unnecessary characters to produce the smallest valid HTML file. For large HTML documents, this can save 10-30% in file size.

Faster HTML parsing and delivery improves Time to First Byte (TTFB) and overall page load speed, both of which affect user experience and Core Web Vitals scores.

Frequently Asked Questions

Is it safe to remove HTML comments?

+

Yes for production builds. HTML comments are invisible to users and add bytes with no benefit. Conditional comments for IE are an exception but are rarely needed today.

Does HTML minification affect SEO?

+

Minification reduces page size which improves load speed, a ranking factor. Content and structure are unchanged, so there is no negative SEO effect.
