Code Beautifier

Why Beautify Your Code?

In modern web development, code is often minified to reduce file size and improve load times. While this is great for performance, it makes the code completely unreadable for humans. That's where our tool comes in. Unminify.me is a powerful and free online code beautifier that instantly transforms dense, minified code into a clean, perfectly indented, and human-readable format. Whether you're a developer trying to debug a third-party library or a student learning from real-world examples, our tool is designed to make your life easier.

Our code formatter supports a wide range of web languages. Use it as a JavaScript beautifier to deobfuscate complex scripts, a CSS prettifier to organize your stylesheets, an HTML formatter to structure your documents, or a JSON and XML viewer to validate and read data structures. Simply paste your code, provide a URL, select your language and tab size, and let our tool do the rest. The result is clean, readable code that you can easily understand, analyze, and work with, boosting your productivity and code comprehension.

Understanding Code Minification

Minification is the process of removing all unnecessary characters from source code without changing its functionality. This includes removing white space, comments, and newlines, as well as shortening variable and function names. The resulting minified file is significantly smaller, leading to faster download times and improved website performance. While essential for production environments, it creates a major challenge when you need to read or debug the code.

What Our Unminify Tool Does (and Doesn't Do)

This tool excels at reversing the structural changes of minification. It re-inserts spaces, tabs, and line breaks to create a logical, readable layout. It does not, however, reverse changes like shortening variable names (e.g., changing `n` back to `customerName`). The original variable names are lost during the minification process. Our tool focuses purely on formatting, making it a fast and reliable code beautifier, not a full decompiler.

How to Use Our Code Beautifier

Using our tool is simple. You have three main options:

• Paste your minified code directly into the "Minified Code" text box.
• Click "Browse" to upload a file from your computer.
• Enter a URL to a raw code file (like from a CDN) and click "Fetch & Beautify".

For any method, ensure you have the correct language (e.g., HTML, JavaScript, CSS, JSON, XML) and desired tab size selected from the dropdown menus. The formatted, easy-to-read code will appear instantly in the "Result" box.
