HTML Formatter

What is an HTML Formatter?

An HTML Formatter rewrites your markup with a consistent two-space indent so tags become easy to scan and edit. Text between tags is trimmed onto its own lines, comments are kept in place, and raw content inside pre, script and style blocks is preserved exactly as written.

How does formatting work here?

• Opening and closing tags are re-indented to reflect nesting depth; void and self-closing tags never add indentation.
• Whitespace between tags is collapsed and inline text is placed on its own trimmed line.
• Content inside pre, script and style is copied as-is — code is never reformatted.
• HTML comments and doctypes are preserved, and malformed HTML never crashes the tool.

What clean indentation reveals

When every open and close tag lines up at the same depth, mismatched tags stand out immediately and nesting becomes obvious at a glance. That visual pattern is the fastest way to spot unclosed sections before a browser does it for you.

Formatting code from templates

Server-rendered or template output is often one long line. Running it through a formatter splits tags into readable rows, which makes debugging the emitted HTML as easy as reading the source template.
