About HTML Prettifier
The HTML Prettifier takes minified, compressed, or poorly-indented HTML and formats it with consistent indentation, making the structure easy to read and navigate. Whether you received a minified HTML file, copied markup from a website, or are working with dynamically generated HTML, this tool instantly makes it readable.
Properly formatted HTML is easier to debug, review, and maintain. The prettifier respects block vs inline element rules, handles nested elements correctly, and preserves important whitespace inside elements like pre and code.
Paste your HTML and copy the formatted result with one click.
