Formats an HTML string or file using your preferred indentation level. The formatting rules are pre-optimized to produce clean and readable output without requiring any configuration. The formatter preserves spaces and tabs inside content elements such as div and span, as these are treated as valid and meaningful content.
HTML is the foundation of every website, but when code is minified or poorly formatted, it becomes difficult to read and maintain. Our free HTML formatter helps you convert messy or compressed HTML into clean, well-structured code with proper indentation and spacing.
Whether you are debugging existing code, learning from online examples, or working with production-ready HTML, readable code is essential. Our formatter automatically analyzes the HTML structure and applies consistent indentation, making it easier to understand the document hierarchy and quickly locate specific elements.
Simply paste your HTML code into the editor or upload an HTML file using the UPLOAD button. You can also drag and drop files directly into the editor area. Click the FORMAT button to instantly transform your code into clean, well-formatted HTML. Adjust the TAB SIZE to match your preferred indentation style. Once finished, use the COPY button to copy the formatted code or DOWNLOAD it as a file.
