Free HTML Formatter & Beautifier

Format and beautify messy HTML code instantly with proper indentation.

About this tool

HTML code often becomes hard to read - especially when it is copied from a browser inspector, minified for production, or generated by a tool. Proper indentation is essential for readability and maintainability. This free HTML Formatter takes any messy, minified, or poorly-indented HTML and instantly reformats it with clean, consistent indentation. The formatter handles all standard HTML elements, correctly identifies void elements (like br, img, input) that should not be indented further, and preserves the content of pre, script, and style blocks without reformatting them. Inline elements like span, a, and strong are kept on the same line to maintain readable output. This tool also includes a Minify mode that strips all unnecessary whitespace from your HTML, reducing file size for production use.

How to use

Step 1: Paste your HTML code in the left input box.
Step 2: Choose your preferred indent size (2 or 4 spaces) and indent type (spaces or tabs).
Step 3: Click Format HTML to beautify the code with proper indentation.
Step 4: Alternatively, click Minify to strip all whitespace for production use.
Step 5: Click Copy to copy the formatted result to your clipboard.

Frequently Asked Questions

HTML formatting (beautifying) is the process of adding proper indentation and line breaks to make HTML code readable. It does not change how the page renders in a browser - only how the source code looks to developers.

HTML minification removes all unnecessary whitespace, comments, and line breaks from HTML to reduce file size. Minified HTML loads slightly faster because there are fewer bytes to transfer, but it is much harder to read.

No. This formatter only adjusts whitespace (indentation and line breaks). The actual HTML tags, attributes, and content remain unchanged. Your page will render identically before and after formatting.

Both work. The most common convention in web development is 2 spaces (used by Google, Airbnb style guides) or 4 spaces. Tabs are a valid alternative, especially if your team prefers them. The most important thing is consistency.

This tool is specifically designed for HTML. The content of script and style tags is preserved as-is. For JavaScript or CSS formatting, use dedicated formatters.
