About this HTML Formatter

HTML pulled from a live site's view-source, a CMS export, or a minified production build is often a single dense line with no indentation, making the structure nearly impossible to read. Formatting adds consistent line breaks and indentation to reveal the nesting of elements.

Why nesting matters for readability

HTML elements nest inside each other — a <div> containing a <ul> containing multiple <li> elements, for example. Proper indentation visually represents that nesting depth, so a glance at the indentation shows which elements are contained inside which, without having to mentally track opening and closing tags across a dense wall of text.

Beautify vs. minify

Beautified HTML is for humans: readable, indented, easy to debug and edit. Minified HTML strips all unnecessary whitespace and line breaks to reduce file size for production delivery, where every byte affects page load speed but human readability doesn't matter since the browser parses it identically either way.

Common uses

  • Cleaning up markup copied from a page's view-source or browser DevTools
  • Reviewing or editing HTML exported from a website builder or CMS
  • Debugging a layout issue by making the element nesting visible
  • Minifying a small HTML snippet before embedding it elsewhere
