JavaScript & TypeScript Minifier - Code Compressor Online

Minify and compress JavaScript/TypeScript code to reduce file sizes. Remove comments, whitespace, and optimize code for faster loading and better performance.

How to Use the JavaScript/TypeScript Minifier

  1. Paste your JavaScript or TypeScript code in the input editor
  2. Click the "Minify" button to compress your code
  3. View the compression statistics to see how much space you've saved
  4. Review the minified output with optimized structure
  5. Copy the minified code using the copy button

What does JavaScript/TypeScript minification do?

  • • Removes all comments and unnecessary whitespace
  • • Eliminates extra spaces around operators and punctuation
  • • Compresses function declarations and control structures
  • • Optimizes arrays, objects, and conditional statements
  • • Maintains functionality while reducing file size
  • • Supports modern ES6+, TypeScript, and JSX syntax

⚠️ Important: Minified code is not human-readable and should only be used for production. Keep your original formatted files for development and debugging purposes.

💡 Pro Tip: For maximum optimization, consider using a dedicated bundler like webpack or Vite with tree-shaking and advanced minification for production builds.

What is a JavaScript/TypeScript Minifier?

A JavaScript/TypeScript Minifier is a tool that removes unnecessary characters (like whitespace, comments, and line breaks) from source code without changing its functionality. This process, also known as uglification, significantly reduces the file size of the script.

Why Use Our JS/TS Minifier?

  • Improved Performance: To reduce the file size of your scripts, leading to faster download times and quicker website loading.
  • Bandwidth Reduction: To save on data transfer costs by serving smaller files to users.
  • Production Optimization: To prepare your code for a production environment where every kilobyte counts.
  • Obfuscation: While not its primary purpose, minification can make code harder to read, providing a basic level of obfuscation.
