Free Online HTML Formatter & Beautifier

The HTML Formatter indents your markup by nesting level so the structure is easy to read. It recognizes void elements (like img and br) so they do not create false indentation.

How to Use

Paste your HTML and click Format. The indented markup appears on the right.

  • Indents by element nesting
  • Handles void elements correctly
  • Keeps text content in place

Note

This is a lightweight formatter for typical HTML. Highly irregular or malformed markup may not indent perfectly — validate with the result before relying on it.
