HTML Formatter & Beautifier
Paste messy or minified HTML and instantly format it with proper indentation. Or minify it for production. Runs entirely in your browser.
Smart Indentation
Handles block vs inline elements correctly — inline tags like <span> and <a> stay on one line.
Pre & Script Aware
Preserves whitespace inside <pre>, <script> and <style> blocks where indentation matters.
100% Private
All formatting happens in your browser. Your HTML never leaves your device.
Why format your HTML?
Well-formatted HTML is easier to read, debug and maintain. When working with templating engines, CMS output, or minified production code, running it through a beautifier instantly makes the structure visible — saving time when hunting for missing closing tags or incorrect nesting.
Minifying HTML removes unnecessary whitespace and comments, reducing file size and improving page load speed — useful before deploying static HTML pages or email templates.
