Auto-indent, clean up, and validate HTML markup locally with support for dynamic spacing and wrapping.
1What is an HTML Formatter?
An HTML Formatter parses cluttered, minified, or disorganized HTML markup and formats it into a neat, nested tree. It automatically adds proper indentation levels, wraps attributes, cleans up tag spacing, and matches start/end tags, making source code legible.
2Example: Before and After
Input HTML:
<div class="card"><h1 id="title">Hello World</h1><p>Welcome to our site.</p></div>
Output HTML:
<div class="card">
<h1 id="title">Hello World</h1>
<p>Welcome to our site.</p>
</div>
3Configurable Layout Styles
Tailor the formatting output to match your frontend coding guidelines. Adjust indent sizes (2 spaces, 4 spaces, or Tabs), configure whether tags like <script> or <style> should be formatted, and choose between wrapping lines at custom character limits.
4Client-Side Security and Speed
Formatting whole HTML pages can involve sensitive layouts or draft content. Our formatter runs completely client-side in your browser. This enables instant formatting of large files without server round-trips or privacy leaks.
