About HTML Formatter & Minifier

HTML from template engines, CMS outputs, and framework renders is often flat, un-indented, and impossible to read. The formatter adds nesting and indentation based on tag hierarchy. Minify removes whitespace and comments — typically 10-20% size reduction. Inline elements (span, a, strong) are handled carefully to avoid introducing unwanted whitespace nodes in the render. Works with HTML5 including web components, custom elements, and embedded SVG.

Common Use Cases

  • →Making CMS or template-generated HTML readable for debugging
  • →Cleaning up HTML exported from design tools
  • →Minifying HTML templates for production
  • →Formatting source code before a code review

Frequently Asked Questions

Does formatting change the rendered output?+
For block elements: no. For inline elements (span, a, em), adding whitespace can introduce tiny rendering differences because whitespace between inline elements is significant. The formatter handles known inline elements carefully.
Does minification remove comments?+
Yes. HTML comments are stripped by the minifier. If you rely on conditional comments (for IE, though that is rare now) or have important build markers in comments, be aware they will be removed.
