Frequently Asked Questions

What's the difference between beautify and minify?

Beautify adds indentation and line breaks to make code readable. Minify removes all unnecessary whitespace to reduce file size for production.

Can I format production code?

Yes! Format production code to make it readable for debugging. Use minify before deploying to reduce bandwidth and improve load times.

Does this validate code syntax?

The formatter attempts to parse and format valid code. Invalid syntax may produce errors. Use this for formatting, not validation.
