Learn how to format and beautify HTML code effectively
What is HTML Formatting?
HTML formatting improves code readability by adding proper indentation and line breaks. Well-formatted HTML is easier to read, debug, and maintain. Minification removes unnecessary whitespace to reduce file size for production.
How to Use This Tool
- Paste your HTML code in the input field
- Select your preferred indentation size
- Click 'Format' to beautify or 'Minify' to compress
- Copy the result using the copy button
Pro Tips
- Use the Sample button to see a properly formatted HTML example
- Self-closing tags like <img>, <br>, <hr> are handled correctly
- Minified HTML loads faster in browsers due to smaller file size
Browser Support
This tool works in all modern browsers. The formatted HTML is compatible with all HTML5-compliant browsers.
Frequently Asked Questions
Does formatting HTML affect how it renders in browsers?
In most cases, no. Browsers ignore extra whitespace in HTML. However, whitespace inside <pre>, <code>, or <textarea> tags can affect rendering. This formatter is designed to preserve meaningful whitespace while adding readability improvements.
What's the difference between Format and Minify?
Format adds indentation and line breaks to make HTML readable for developers. Minify removes all unnecessary whitespace to reduce file size for faster loading in production. Use Format during development and Minify for deployment.
Why are some of my inline styles on separate lines?
The formatter prioritizes readability by breaking long lines. For inline styles, consider moving them to a separate CSS file or <style> block, which is a best practice for maintainability and caching.
Can this tool validate my HTML?
This tool formats HTML but doesn't strictly validate it against HTML5 specifications. It handles common HTML patterns gracefully, including self-closing tags and void elements. For strict validation, use the W3C HTML Validator.
How does it handle script and style tags?
Content inside <script> and <style> tags is preserved as-is to avoid breaking JavaScript or CSS code. The formatter only adjusts the indentation of the tags themselves, not their internal content.
