Frequently Asked Questions

What does an HTML Formatter / Beautifier do?

An HTML Formatter (or Beautifier) takes potentially messy or unformatted HTML code and automatically rearranges it according to standard coding conventions. It adds consistent indentation, line breaks, and spacing to make the code structure clear and easy for humans to read, without changing the way the browser renders the page.

Why should I format my HTML code?

Formatting HTML greatly improves its readability and maintainability. It helps you (and others) quickly understand the structure of the document, locate specific elements, identify nesting issues, and debug problems more efficiently. Consistent formatting is also essential for teamwork.

How does this tool work? Is my code uploaded?

This tool uses the popular Prettier library running directly in your web browser via JavaScript. When you input your HTML and click "Format HTML", the JavaScript code processes it locally on your device. Your HTML code is never uploaded to our server, ensuring privacy and speed.

Can I customize the indentation (spaces or tabs)?

Yes! Use the "Indentation" dropdown menu above the output area to choose between using 2 spaces, 4 spaces, or a tab character for each level of indentation in the formatted code.

Will this tool fix errors in my HTML?

No, this tool is a formatter, not a validator or fixer. It assumes your input HTML is syntactically valid, even if messy. If your HTML has significant errors (like unclosed tags), the formatter might fail or produce unexpected results. Its purpose is to improve the structure and readability of valid code, not correct functional errors.

Is this HTML formatter free to use?

Yes, this tool is completely free for anyone to use online, with no limitations or registration required.
