FAQ

Are script and style tags stripped during minification?

No. Their contents stay untouched. Use the dedicated JS and CSS minifiers separately before inlining them into HTML.

Does my code get sent to a server?

No. Formatting and minification run entirely in your browser via JavaScript. Nothing is ever uploaded.
