How to Use This Tool

Optimize and clean your website code with our advanced HTML Formatter tool. This essential utility helps developers and designers beautify, validate, and compress HTML markup for improved readability and performance.

Start by pasting your minified or messy HTML code into the Input HTML text area. Use the Example button to load sample code or Clear to start fresh. Click the "Format HTML" button to process your code instantly.

Customize the output using the Formatting Options. Choose your preferred Indentation Type (Spaces or Tabs) and Indentation Size (2, 4, or 8 spaces) to match your project's coding standards. Toggle options to Wrap Attributes for vertical alignment, Preserve Newlines, or limit consecutive empty lines.

The tool displays your beautifully formatted code in the Formatted Output section. Review the line and character count statistics to track changes. Use the Copy button to easily transfer the code to your editor, or Download it as a .html file for immediate use.

Ensure code quality with the HTML Validation feature. Click "Validate HTML" to check for syntax errors, missing tags, or other issues that could affect website performance and SEO. The validator provides clear feedback and warnings.
