Questions

How do I format messy HTML code?
Paste your unformatted HTML into the input field and the tool will instantly reformat it with consistent indentation and line breaks, making the tag hierarchy easy to read and edit.
Does the HTML formatter change my code behavior?
No, the formatter only adjusts whitespace and indentation. It does not alter tag names, attributes, or content, so your HTML will render identically in the browser after formatting.
Is the HTML formatter safe to use with sensitive code?
Yes, all formatting happens locally in your browser. Your HTML is never uploaded to a server, so proprietary markup and content remain private on your device.
Can I use the HTML formatter offline?
Once the page has loaded, the formatter runs entirely in your browser using client-side JavaScript. You can disconnect from the internet and it will continue to work.
How does the HTML formatter compare to Prettier or VS Code formatting?
This tool provides quick, zero-config formatting directly in your browser without installing anything. For project-wide formatting with custom rules, a local tool like Prettier offers more configuration options.
