HTML Minifier & Beautifier
Compress HTML (including inline CSS and JS) or make messy markup readable — 100% in your browser
What does HTML minification do?
HTML minification removes the bytes browsers ignore: indentation, line breaks, runs of spaces and comments. This tool uses html-minifier-terser with safe settings — it collapses whitespace, strips comments, and also minifies any inline CSS inside <style> tags and inline JavaScript inside <script> tags, so a complete page is compressed in one pass. Whitespace-sensitive elements like <pre> and <textarea> are left untouched.
Typical savings are 10–25% for plain markup, and considerably more for deeply indented template output or pages with large inline styles and scripts. On a 100 KB HTML document that is 10–25 KB the browser no longer has to download and parse — HTML is the first, blocking resource of every page load, so those bytes directly affect Time to First Byte-to-render.
Beautify mode does the opposite: it re-indents minified or messy markup with consistent nesting so the document structure is easy to read — handy for inspecting a page you saved from production or cleaning up generated HTML.
