About HTML Formatter
The formatter only changes whitespace between tags; it never adds or removes elements, so broken HTML stays as it is. Inline elements such as links and bold text stay on the line with their text. Content inside pre and textarea is left untouched.
Everything runs in this browser tab: your text is never uploaded or stored, and the result updates as you type. It keeps working offline once the page has loaded.
