JavaScript Beautifier
Format and indent JavaScript code.
About this tool
Minified JavaScript is fast to load but hard to read and edit. Our JavaScript beautifier takes minified or messy JS and reformats it with clear indentation and line breaks. Paste your code, click beautify, and copy the result. Useful when you need to inspect or modify third-party scripts or old bundles. Everything runs in your browser; your code stays on your device. No sign-up, no limits. A simple way to make JavaScript readable again.
How to use
Paste minified or messy JavaScript and click Beautify. Indentation and line breaks are applied for readability.
