Understanding the Results
What is the beautified code?
The output is your original code, but rewritten with a consistent and clean format. The logic and functionality are identical, but all spacing, indentation, and line breaks have been standardized according to the official style guide for that language. This makes the code significantly easier for you and other developers to read and understand.
Where should I use this code?
Beautified code is for **development environments**. You should use the clean, formatted version of your code in your code editor (like VS Code) while you are building and debugging your project. It helps you spot errors and work more efficiently. Before you deploy your website to a live server, you should use a Code Minifier to compress it for the best performance.

Beautify Code NowFrequently Asked Questions
Why should I beautify my code?
Clean, well-formatted code is easier to read, debug, and maintain. It improves collaboration among developers and reduces the chance of errors. For production websites, minifying code is better for performance, but during development, beautified code is essential for clarity.
Is this tool free to use?
Yes, absolutely. Our Code Beautifier is 100% free to use with no limitations on how much code you can format.
Is it safe to paste my code here?
Yes. All code formatting and beautification happen entirely within your web browser using JavaScript. Your code is **never** sent to our servers, ensuring your work remains completely private and secure.
What is the difference between "Beautify" and "Minify"?
They are opposites. **Beautifying** (or formatting) adds whitespace and line breaks to make code readable for humans during development. **Minifying** removes all unnecessary characters to make the file size as small as possible for faster loading on a live website.
Does this tool send my data to a server?
No. All code formatting happens entirely within your browser using the Prettier JavaScript library. Your code is never sent to our server, making this tool fast, secure, and completely private.
