What is an HTML Formatter?

An HTML Formatter is a free online tool that beautifies and formats your HTML code with proper indentation, consistent tag formatting, and clean structure. Whether you are dealing with minified HTML from build processes, poorly indented template code, or auto-generated markup, this formatter transforms it into clean, readable, and well-structured HTML that follows best practices.

Why format your HTML?

Clean HTML is the foundation of accessible, maintainable web pages. Properly formatted HTML makes it easy to understand the document structure, locate specific elements, identify nesting errors, and collaborate with team members. It also helps with debugging — when your HTML is well-indented, you can quickly spot unclosed tags, misplaced elements, and structural issues.

How to use the HTML Formatter?

Paste your HTML into the input panel. The formatter instantly restructures it with proper indentation showing the nesting hierarchy, consistent attribute formatting, and clean line breaks between elements. You can choose your indentation style (2 or 4 spaces, tabs) and copy or download the formatted output. The tool preserves your HTML content while improving its readability.
