FAQ
?What does minification do?
Minification removes formatting, whitespace, and comments from your code. The browser doesn't need these to understand the code, so removing them makes the file download faster.
?Is my code sent to a server?
No. This tool runs 100% locally in your web browser. Your proprietary code is never transmitted or stored anywhere.
?Will minification break my code?
While basic minification is generally safe, it's always recommended to test your minified code. Ensure your JavaScript doesn't rely on automatic semicolon insertion before minifying.
