HTML Beautifier – Format & Indent HTML Code Online Free
About the HTML Beautifier
The HTML Beautifier takes messy, minified, or poorly formatted HTML and reformats it into clean, properly indented code. Paste your HTML, choose your preferred indent size and character, and the tool restructures your code with consistent line breaks and nesting — making it easy to read, debug, and maintain. If you need to shrink your code instead of formatting it, try the HTML Minifier.
This tool is built for developers and website owners who need to inspect, edit, or clean up HTML pulled from a minified source, an old file, or someone else’s code. It intelligently preserves the content inside <pre>, <script>, and <style> tags so formatting-sensitive code isn’t disrupted during the process. Once your HTML is clean, you can also check text formatting with the Case Converter for any embedded copy.
Our team tested this tool on a range of real-world HTML files — from single-page landing sites to deeply nested, minified templates — to confirm indentation stays accurate and <script>/<style> content is never broken during formatting.
How to Use the HTML Beautifier
- Paste your unformatted HTML code into the HTML Input box.
- Choose an Indent Size: 2, 4, or 8 spaces.
- Choose an Indent Character: Space or Tab.
- Click Beautify HTML to generate the formatted result.
- Review the Original Size, Beautified Size, and Size Difference stats.
- Click Copy Code or Download .html to save your formatted file.
Example Usage
Input:
<div class="example"><p>Hello World</p></div>
Output (2-space indent):
<div class="example">
<p>
Hello World
</p>
</div>
This makes deeply nested or minified HTML far easier to read, review, and debug in an editor.
