常见问题
Will formatting change how my HTML renders?
No. Formatting only adds whitespace for readability. Browsers ignore extra whitespace when rendering.
Can I format partial HTML fragments?
Yes. You can format HTML snippets, not just full documents. The parser wraps fragments for processing.
Is this tool free?
Yes. This tool is completely free to use with no sign-up, no limits, and no hidden fees.
Does my data leave my browser?
No. All processing happens entirely in your browser using client-side JavaScript. Your data is never sent to a server or stored anywhere.
