What Does HTML Formatting Do?

Beautify adds proper indentation and line breaks to nested tags, making complex HTML structures readable and maintainable. Minify removes all unnecessary whitespace between tags, reducing file size for faster page loads.

The formatter handles self-closing tags, inline elements, pre/code blocks (preserving their whitespace), and deeply nested structures. It does not modify attributes, content, or tag order.
