Frequently Asked Questions

When using HTML Formatter, what formatting rules does it apply?

Proper indentation (configurable 2 or 4 spaces), attribute alignment, closing tag consistency, logical nesting hierarchy, and blank line separation between major sections.

Does it handle inline styles and scripts?

Yes. HTML with inline styles, script tags, and embedded CSS is formatted correctly. The content inside script and style tags is preserved without modification.

Can it format minified HTML?

Yes. Paste minified or compressed HTML and the formatter will expand it with proper indentation and structure for readability.

Will it change my HTML semantics?

No. The formatter only adjusts whitespace, indentation, and formatting. It does not add, remove, or reorder any HTML elements or attributes.

Is my HTML stored or transmitted?

No. All formatting happens locally in your browser. No markup is sent to any server.
