How to Unminify HTML Online

HTML unminification restores readable formatting to compressed HTML documents. Paste any minified HTML into our tool and click Unminify to add proper indentation, organize nested elements, and format attributes. This is essential for debugging production websites, inspecting minified templates, or reviewing HTML generated by CMS platforms.

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.
