You can minify JavaScript, CSS, and HTML. The tool automatically detects and compresses any of them.
Does this remove all comments?
Yes. It removes all JS, CSS, and HTML comments to reduce file size and protect code.
Is my code sent anywhere?
No. All processing happens inside your browser. Nothing is uploaded, ever.
Will this break my code?
This tool performs basic minification. For complex JS frameworks, always test before deployment.
Can I undo the minification?
No. Minification is one-way. Always keep a copy of your original source code before minifying.
