HTML Beautifier
Instantly format and beautify HTML code. Convert minified HTML to clean, readable, well-indented code. Free online tool, no registration required.
What does an HTML beautifier do?
An HTML beautifier reformats minified or messy HTML code by adding proper indentation, line breaks, and spacing to make it easy to read, debug, and maintain. It does not change the actual content or functionality of the HTML.
What indentation options are available?
You can choose between 2-space, 4-space, or tab indentation to match your coding style preferences or team conventions.
Is my HTML code sent to a server?
No, all formatting is performed locally in your browser using JavaScript. Your code never leaves your device, ensuring complete privacy and security.
Will beautification change how my HTML renders?
No, beautification only changes whitespace and formatting. The rendered output in the browser remains completely identical since HTML ignores extra whitespace.
What is minified HTML?
Minified HTML is HTML code that has been compressed by removing all unnecessary whitespace, comments, and line breaks to reduce file size and improve page load speed. While efficient for production, it is very difficult for humans to read.
Why do I need to beautify HTML?
Beautifying HTML is essential for debugging, code review, learning HTML structure, understanding third-party code, and making minified code editable. It saves significant time compared to manual formatting.
Can this tool handle large HTML files?
Yes, the beautifier is optimized to handle large HTML files efficiently. Processing happens in your browser, so performance depends on your device capabilities.
Does the beautifier fix broken HTML?
The beautifier properly formats well-formed HTML. For severely broken HTML with unclosed tags or syntax errors, it will still attempt to format the structure but may not fix all issues.
Is this tool free to use?
Yes, this HTML beautifier is completely free. There are no hidden fees, no registration required, and you can use it as many times as you need.
Can I paste HTML from a website?
Yes, you can paste any HTML code into the input area. You can copy HTML source code from any webpage using your browser's developer tools (View Source or Inspect Element) and paste it here for formatting.
What is the difference between HTML beautifier and HTML validator?
An HTML beautifier focuses on formatting and readability by adjusting whitespace and indentation. An HTML validator checks the code against HTML standards and reports errors or warnings. This tool beautifies the code structure.
Does it support HTML5?
Yes, the beautifier fully supports HTML5 and all previous HTML versions. It correctly handles all standard HTML tags, attributes, and structures.
How to Use HTML Beautifier
HTML Beautifier turns minified or messy HTML into clean, readable, well-indented code. Everything runs locally in your browser, so your code is never uploaded.
- Paste your minified or messy HTML into the "Input HTML" box.
- Choose an indentation style from the "Indent:" menu: "2 Spaces", "4 Spaces", "8 Spaces", or "Tab".
- The formatted result appears in the "Beautified HTML" box, re-indented and easy to read.
- Copy the "Beautified HTML" output back into your editor or project.
Whitespace changes can affect rendering inside <pre> tags and inline text, so double-check those areas after beautifying.
