Free online HTML formatter and beautifier. Paste minified or messy HTML and instantly format it with proper indentation for readability.
Minified HTML is compact and fast for browsers to parse but unreadable for humans. Build processes, CDNs, and web scrapers often produce HTML without whitespace or indentation. This formatter restores human-readable structure with proper nesting and indentation.
This free HTML formatter takes any HTML input — minified, scraped, or just messily written — and outputs cleanly indented HTML with each element on its own line and consistent 2-space indentation for nested elements.
Formatted HTML is essential for debugging layout issues, reviewing scraped page source, understanding third-party HTML structures, and maintaining code quality in HTML templates. The visual hierarchy of properly indented HTML makes the document structure immediately obvious.
The formatter uses 2-space indentation by default, which is the most common convention in web development. Each level of HTML nesting adds 2 spaces of indentation.
No. Whitespace between HTML elements is generally insignificant in browsers. The formatted HTML renders identically to the minified version. The only exception is text inside <pre> tags, where whitespace is preserved as-is.
The formatter processes HTML as-is and does not validate it against HTML standards. Invalid or unclosed tags will be formatted as they appear. For HTML validation, use the W3C Markup Validation Service.
Yes. The formatter works on any HTML input — complete documents with <!DOCTYPE> and <html>, partial templates, or individual component snippets.
