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.

FAQ

• Does this change my JavaScript or CSS? No — anything inside script, style and pre tags is kept byte-for-byte; only the surrounding indentation changes.
• Can I re-format the output again? Yes, formatting is idempotent: feeding the formatted result back in produces the same clean output.
• Is my HTML uploaded anywhere? No — formatting runs entirely in your browser and your markup never leaves your device.
