How this HTML Pretty Print works

This HTML formatter takes minified or poorly indented HTML markup and reformats it with consistent indentation, proper line breaks, and structured nesting. It parses your raw HTML input, reconstructs the document tree, and serializes it back with clean, readable spacing. The tool handles inline elements, block elements, nested structures, and embedded style or script tags without corrupting the markup.

All formatting runs entirely in your browser using JavaScript. Your HTML is never uploaded to a server, making it safe for formatting code that contains proprietary templates, internal URLs, or sensitive page structures. Processing is instantaneous regardless of file size for typical web documents.

For deeper debugging, run your markup through our HTML Validator to identify structural errors and missing tags.

The pretty printer is useful for developers debugging third-party HTML snippets, designers reviewing page structure, or anyone working with minified CMS exports. It supports configurable indentation size and preserves HTML comments. The cleaned output is easier to read in code reviews, diff comparisons, and documentation.
