HTML
Beautifier

No. The beautifier only adds or modifies whitespace characters (spaces and newlines). Text content, attribute values, and tag names are preserved exactly.

Script content is indented as a block but not reformatted as JavaScript. Style content is similarly preserved. Use the JS or CSS beautifiers for those separately.

Yes. Choose 2-space, 4-space, or tab indentation.

The beautifier parses the HTML structure to indent it, so malformed HTML may produce unexpected results. It is not a validator — use an HTML validator for structural checks.

There is no hard limit. Typical HTML documents are formatted without issues.
