HOW TO USE

Paste JavaScript and choose fast or deep mode. Review mangling and debug-removal switches before minifying.

function sum(a,b) { return a + b; } keeps its behavior after default minification.

Test minified code in your application. Removing console calls can also remove their argument side effects.
