HTML Formatter

Beautify or minify HTML markup. Free, runs entirely in your browser — no signup, and nothing you paste in is uploaded.

HTML is more forgiving than XML and that is exactly why formatting helps: browsers silently repair unclosed tags and mis-nesting, so a document can render perfectly and still be structurally wrong. Indenting it is often how you discover the `</div>` that was never opened.

Whitespace in HTML is not free, though. Inline elements collapse runs of spaces to one, but they do render that one, so reformatting can add or remove a visible gap between two inline items. Block-level markup reindents safely; a row of inline-blocks is where a pretty-printer can change the layout.
