Frequently Asked Questions
Does this tool validate my HTML?
No — HTML is forgiving, so the tool formats what you paste even if tags are unclosed. Use an HTML validator for strict checking.
Does formatting change how my page looks?
No. It only changes whitespace and indentation in the source; browsers render it the same way.
Can it format a whole page?
Yes. Paste a full document or a fragment — both are formatted.
Is my HTML uploaded anywhere?
No. Formatting runs entirely in your browser.
