Does HTML beautification change the rendered output?

No. Whitespace between block elements doesn't affect rendering. The visual appearance of the page is identical — only the code readability is improved.

Can I set indentation size?

Yes. Choose between 2-space, 4-space, or tab indentation to match your team's coding standards.

Will it handle malformed HTML?

The beautifier attempts to format the HTML as given, but malformed HTML (unclosed tags, mismatched nesting) may produce unexpected formatting. Valid HTML produces clean output.

Can I use this for email template HTML?

Yes. Email HTML is often written in a condensed style. Beautifying it makes the table-heavy layout readable for debugging compatibility issues across email clients.

What is the difference between HTML formatting and linting?

Formatting adds whitespace and indentation for readability. Linting validates HTML against standards, flagging errors and accessibility issues. This tool formats; use a validator for linting.
