What is HTML Formatting?
HTML formatting transforms minified or poorly formatted HTML code into clean, readable markup with proper indentation and structure. Well-formatted HTML is easier to read, debug, and maintain.
This tool adds proper indentation, places each element on its own line when appropriate, and preserves the document structure. It handles all standard HTML elements including void elements.
All processing happens in your browser. Your HTML code never leaves your device and is not sent to any server.
Formatting Features

Line Breaks: Block elements are placed on separate lines.
Void Elements: Self-closing tags (br, img, input, etc.) are handled correctly.

Structure Preservation: Document structure and element order are maintained.

Frequently Asked Questions
Does formatting change the HTML output?
No, formatting only changes whitespace and indentation. The rendered output in a browser will be identical to the original HTML.
How are void elements handled?
Void elements like br, img, input, and meta are recognized and formatted correctly. They don't increase indentation since they cannot have children.
Should I use formatted or minified HTML in production?
Use minified HTML in production to reduce file size. Use formatted HTML during development for easier debugging and readability.
Is my data secure?
Yes. All formatting happens entirely in your browser using JavaScript. Your HTML code never leaves your device and is not sent to any server.
