How it works

  1. Paste HTML — minified page or template fragment.
  2. Formatted output — nested tags indented.
  3. Copy — readable markup for review or docs.

Indentation rules

Block elements get new lines and nested indentation. Inline elements stay compact where possible.

Minify for production

After editing, compress with the HTML Minifier before deployment.
