Instantly indent and format messy HTML into clean, readable code
The HTML Beautifier transforms minified or poorly indented HTML into clean, properly structured code with consistent indentation. Choose between 2 spaces, 4 spaces, or tabs, optionally wrap long attribute lists onto separate lines, and go from a wall of collapsed markup to readable, maintainable HTML in one click — no installation or sign-up required.
It parses your HTML and re-outputs it with consistent indentation, placing each block-level tag on its own line at the correct depth. The result is readable, maintainable markup that is easy to debug or share with teammates.
No. The beautifier only adjusts whitespace between tags. Text content, attribute values, inline elements, and raw blocks like <script> and <style> are preserved verbatim, so the rendered output of your page stays identical.
When enabled, elements with multiple attributes are split so each attribute appears on its own indented line. This is useful for long tags such as form inputs or custom components where readability matters more than line length.
Yes. Click the Minify button to collapse all whitespace between tags into a single compact string — ideal for reducing file size before deploying to production.
