The attributes-on-new-lines option is exactly what I needed for reviewing long React JSX props. Makes multi-attribute components readable at a glance without reformatting in my editor.

I paste API-generated HTML snippets to review before including them in templates. The beautifier makes 400 chars of minified markup instantly readable. Live mode is a great touch.

Tag count and max depth stats are a useful quick indicator of markup complexity. The minify output cut my email template from 18KB to 11KB. Clean, fast, private.

Best free HTML formatter I have tried. The void tag handling is correct — br, img, input don't get a spurious closing indent. A tool built by someone who actually knows HTML.

An HTML beautifier formats HTML markup with consistent indentation and line breaks, making it human-readable. It helps debug nested structures and prepare code for version control or review.
Does it validate HTML?+
This tool focuses on formatting rather than strict validation. It handles well-formed HTML. For full W3C validation use the Nu Html Checker at validator.w3.org.
What are void elements?+
Void elements (br, img, input, meta, link, hr, etc.) cannot have child elements and do not need closing tags in HTML5. This formatter correctly handles them without adding spurious indentation.
How does minification differ from compression?+
HTML minification removes whitespace and comments in the source file. Gzip/Brotli compression is applied by the web server at the network layer — these are complementary, not alternatives. Minify first, then serve compressed.
Does it support HTML5, SVG, and custom elements?+
Yes. The tokeniser handles any tag name including HTML5 semantic elements (article, nav, main), SVG elements and custom web component tags (my-component).
