How to Use

Instructions:

Select your code language (JavaScript or TypeScript)
Configure minifier options based on your needs
Paste your code in the input area
Click "Minify Code" to compress your code
Copy the minified code for use in production
Use "Load Sample" to see an example

✨ Auto-Detection: The tool automatically detects TypeScript code and strips type annotations before minification. TypeScript types are removed, leaving pure JavaScript output.

Minifier Options:

Compress Code: Removes dead code, optimizes expressions, and reduces file size
Mangle Names: Shortens variable and function names to single letters (a, b, c, etc.)
Remove Comments: Strips all comments from the code
Remove Console: Removes console.log, console.info, and console.debug statements

Use Cases:

Reduce JavaScript/TypeScript file size for faster page loads
Optimize production builds for web applications
Remove debugging code before deployment
Obfuscate code structure for basic protection
Prepare libraries for distribution (npm packages)

Example:

Before (readable):

function greet(name) {
  if (name) {
    return 'Hello, ' + name;
  }
}

After (minified):

function greet(n){if(n)return'Hello, '+n}

Note: This tool uses Terser, an industry-standard JavaScript minifier. Always test minified code thoroughly before deploying to production.
