Read MoreFrequently Asked Questions
Is my JavaScript code sent to a server?
➕
No, all processing happens entirely in your browser. Your code never leaves your computer, ensuring complete privacy.
Does this tool work offline?
➕
Yes! After the initial page load, all the required libraries are cached by your browser, allowing you to use the formatter without an internet connection.
What JavaScript versions does this support?
➕
Our formatter supports all modern JavaScript syntax including ES6+ features. It also handles JSX (React) and can be configured to work with TypeScript.
Can I format minified JavaScript code?
➕
Absolutely! Our tool is perfect for making minified code readable again. Just paste your minified code and click format.
Is there a limit to code size?
➕
There's no hard limit, but very large files (10,000+ lines) may slow down your browser since processing happens client-side.
