JavaScript Beautifier
Enter your values and click beautify to see the results.
Turn minified or messy JavaScript into clean, readable code.
About this Tool
JavaScript is often minified for production, turning hundreds of lines into a single, unreadable block of text. This is great for website speed, but terrible when you need to debug a problem or understand what the code actually does.
Our free JS Beautifier takes that compressed, impossible-to-read JavaScript and transforms it back into clean, properly indented code with clear formatting. It is perfect for developers who need to inspect third-party scripts, review obfuscated code, or simply clean up messy files.
The entire process happens instantly in your browser, so your code is never sent to any server. No signup, no installation, just paste and beautify.
How to Use
Paste your messy JavaScript code into the input box.
Click the Beautify button.
The tool will add proper spacing and indentation automatically.
Copy your formatted code using the copy button.
