❓ Frequently Asked Questions

What is JavaScript minification?

Minification removes unnecessary characters from code without changing functionality, reducing file size for faster loading.

Is minification safe for my code?

Yes! Minification only removes whitespace, comments, and optionally shortens variable names. The functionality remains identical.

What's the difference between minification and uglification?

Minification removes whitespace and comments. Uglification goes further by renaming variables, removing dead code, and optimizing syntax.

Can I reverse minified code?

You can beautify minified code to make it readable again, but original comments and variable names (if shortened) cannot be recovered.

Should I minify during development?

No, minify only for production. During development, use readable code for easier debugging and maintenance.

Does this tool support ES6+ syntax?

Yes! This tool supports modern JavaScript including ES6+ features like arrow functions, destructuring, and async/await.

How much can minification reduce file size?

Typically 20-40% reduction, depending on code style, comments, and whitespace. Enabling variable shortening can increase savings.

Is my code sent to a server?

No! All processing happens in your browser. Your code never leaves your device, ensuring complete privacy and security.
