How to Unminify HTML Online

HTML Minification — What Gets Removed

HTML minification removes unnecessary whitespace between tags, HTML comments, optional closing tags, redundant attributes, and empty attribute values. It preserves all content, inline styles, scripts, and structural elements. Your page will render identically in all browsers after minification. Minification does not escape untrusted text for safe HTML output—when you need to preview or debug entity escaping on a snippet, use our HTML entities tool.
