What This Tool Does
Parses HTML and re-formats it with consistent indentation. Inline elements (span, a, strong, etc.) are kept on the same line as surrounding content to preserve rendering fidelity. Void elements (br, img, input, etc.) are not given closing indentation. Pre, script, and style blocks are preserved as-is.
Frequently Asked Questions
Does formatting change the rendered output?
No. HTML formatting only adds whitespace (indentation and newlines) between tags. Browsers collapse whitespace in HTML rendering, so a formatted and minified version of the same HTML produce identical visual output.
Are inline elements treated differently?
Yes — the formatter preserves inline elements (span, a, strong, em, etc.) on the same line as their surrounding text to avoid introducing unwanted whitespace that could affect rendering in some edge cases.
Is my code sent to a server?
No. Formatting runs entirely in your browser. Nothing is transmitted.
