Yes, all JavaScript formatting happens locally in your browser. Your code is never sent to any server. This makes it safe to format proprietary code, API keys, or sensitive business logic without any privacy concerns.
The JS formatter supports all modern JavaScript including ES6+ features like arrow functions, template literals, destructuring, spread operators, async/await, classes, modules, optional chaining, and nullish coalescing. It handles both browser and Node.js code, as well as JSX syntax for React.
Yes, paste any minified or compressed JavaScript and the formatter will beautify it back into readable, properly indented code. This is useful for debugging production code, understanding third-party scripts, or reformatting bundled output.
