HTML Formatter
Pretty-print minified or messy HTML with consistent indentation.
Worth Knowing
Indenting HTML exposes the nesting of elements, which is where most layout bugs live — an unclosed tag or a div nested one level too deep is obvious in formatted markup and invisible in a minified blob. Browsers are famously forgiving and will silently 'fix' broken HTML in ways that differ between them, so clean, well-structured source is your best defense against inconsistent rendering. Formatting also makes it far easier to spot accessibility issues like missing alt attributes or unlabeled form fields.
How to Use
