Frequently Asked Questions
Does formatting change how the HTML renders?+
No. Adding whitespace and indentation to HTML has zero effect on how browsers render the page. Formatted HTML is purely for developer readability and maintainability — browsers ignore extra whitespace between tags.
Can I use this for XML?+
Basic XML can be formatted with this tool since HTML is a subset of SGML. For strict XML validation and formatting with namespace support, use our dedicated XML Formatter tool instead.
