Why Use This HTML Minifier
Minifying HTML removes whitespace, comments, and optional attributes to reduce page load times. This tool preserves inline <style> and <script> blocks correctly, so your embedded CSS and JS remain intact.
The beautifier reformats minified or messy HTML with proper indentation, making it easy to read and debug. It correctly handles void elements like <br>, <img>, and <input>.
