Frequently Asked Questions

What is HTML formatting and why is it important?

HTML formatting involves organizing and structuring HTML code with proper indentation, line breaks, and spacing. It's important for code readability, maintainability, team collaboration, and debugging.

What's the difference between beautify and minify?

Beautify adds proper indentation, line breaks, and spacing to make code readable. Minify removes unnecessary whitespace and characters to reduce file size for production use.

Is my HTML code secure when using this tool?

Yes, all processing is done locally in your browser. Your HTML code is never sent to our servers or stored anywhere, ensuring complete privacy and security.

Can I format large HTML files?
