How do I format HTML online?

Paste your HTML into UtiliTools HTML Formatter and click Format. The tool uses the browser-native DOMParser to parse your markup and recursively serializes it with proper indentation. Choose between 2 spaces, 4 spaces, or tab indentation.

Does the HTML formatter handle void elements?

Yes, the formatter correctly handles all HTML void elements like br, hr, img, input, meta, and link. These elements are rendered as self-closing tags without accidentally adding closing tags.

Are script and style tags preserved?

Yes, the formatter preserves the content of script, style, and pre tags exactly as written. Only the surrounding HTML structure is reformatted with proper indentation.

What is HTML minification?

HTML minification removes unnecessary whitespace, newlines, and indentation between tags to reduce file size. This can improve page load times by reducing the amount of data transferred over the network.

Is my HTML data private?

Absolutely. UtiliTools processes all HTML formatting entirely in your browser using the native DOMParser API. Your markup is never sent to any server, making it safe for proprietary templates and sensitive code.
