About the HTML Formatter
The HTML Formatter cleans up messy or minified HTML by adding consistent indentation and line breaks, so you can see the structure of the page. It is useful when you copy markup from a website, an email template, a CMS editor or a minified build, and need to read or edit it.
How to Use the HTML Formatter
- Paste your HTML into the input box.
- Click Format.
- Review the indented result and look for unclosed or wrongly nested tags.
- Copy the formatted HTML back into your editor.
Why Clean HTML Matters
Properly indented HTML makes it easy to see which elements are inside which, find missing closing tags and understand layout problems. It makes code reviews and team collaboration much faster, and reduces mistakes when editing templates by hand.
HTML Best Practices
Use semantic elements such as <header>, <nav>, <main>, <article> and <footer> instead of only <div>. Use one <h1> per page and keep headings in order. Add alt text to images, labels to form inputs, and avoid inline styles where a CSS class will do. These habits help accessibility and SEO.
Formatting vs Minifying
Formatted HTML is for development. For production, your build pipeline or server can minify HTML, CSS and JavaScript and enable gzip or Brotli compression, which reduces download size without changing how the page looks.
Frequently Asked Questions
Does formatting change how my page looks?
In almost all cases no. Whitespace between block elements is ignored by browsers. Be careful inside <pre> tags and between inline elements, where spaces can be visible.
Will it fix broken HTML?
Formatting makes problems easier to see, but you should still fix unclosed or mis-nested tags yourself.
Can I format email templates?
Yes, table-based email HTML formats well and becomes much easier to edit.
Does it format inline CSS and JavaScript?
It focuses on HTML structure. Use the CSS Minifier and a JavaScript formatter for those parts.
