JS Minifier – User Guide

📘 Overview

JS Minifier compresses JavaScript by removing unnecessary characters like whitespace, comments, and line breaks—making your code smaller and faster to load in production.

✅ How to Use

  1. Open the Tool: Use an online version (e.g., javascript-minifier.com) or a local/CLI-based minifier.
  2. Paste or Upload Code: Insert your JavaScript into the input box or upload a .js file.
  3. Click Minify: Press the Minify/Compress button to start the process.
  4. Copy or Download Output: Copy the minified code or download it as a `.min.js` file.

🧪 Example

🔹 Original Code:

function greet(name) {
    console.log("Hello, " + name);
}
greet("John");

🔹 Minified Output:

function greet(n){console.log("Hello, "+n)}greet("John");

⚙️ Advanced Options

  • Mangle variable and function names
  • Remove console/debug statements
  • Preserve license comments with config flags
  • Generate source maps for debugging

🚨 Tips & Notes

  • Always keep a backup of the original code.
  • Use minified code only in production environments.
  • Consider source maps for post-minification debugging.
