Frequently Asked Questions
Getting Started
What is an HTML formatter?
An HTML formatter restructures raw or minified HTML markup with proper indentation and line breaks so that the document tree is visually apparent. It handles standard HTML elements, void elements, inline elements, and preserves content inside script and style tags.
Is this HTML formatter free?
Yes. All tools are completely free and run locally in your browser. No signup, no limits, no hidden costs.
Does the tool store my code?
No. Your HTML code never leaves your browser. All processing happens locally on your device, ensuring complete privacy and security.
Features & Usage
How does the formatter handle void elements?
Void elements (br, img, input, meta, etc.) are correctly identified and are not indented as containers with closing tags. The formatter knows these elements have no children.
Does it preserve content inside script and style tags?
Yes. Content inside script and style elements is left unchanged. The formatter recognizes these as raw text elements and does not attempt to indent or reflow their inner content.
Can I format partial HTML snippets?
Yes. You do not need a full document. The formatter works on any valid HTML fragment, such as a single div block, a table, or a form.
Troubleshooting
Will minifying HTML affect how the page renders?
Minification removes whitespace between tags, which can affect inline and inline-block elements. Test your minified HTML if exact inline spacing matters for your design.
Can I use this tool offline?
Yes! Once you've visited the page, all functionality works offline thanks to service workers and local processing.
