❓ Frequently Asked Questions
Is my code safe?
Yes! All code formatting is done using JavaScript directly in your browser. Your code is never sent to our servers.
Can I format minified code?
Absolutely! Our beautifier is perfect for un-minifying code to make it readable again.
Does it fix syntax errors?
The formatter focuses on layout and indentation. While it can handle some basic structure issues, it does not fix syntax errors.
Is there a limit on code size?
Since processing is done on your device, the limit depends on your browser's memory. It can easily handle files with thousands of lines.
