JS Minifier

Welcome to the JS Minifier tool! This tool helps you reduce the size of your JavaScript code by removing unnecessary spaces, comments, and line breaks.

How to use:

• Paste your JavaScript code in the Paste JS Code box OR enter a direct JS file URL in the Or enter JS file URL box.
• Click the Minify Now button below.
• Your minified JS will appear below, along with original and minified size information.

Sample JS:

// Example JS
function hello(name) {
    // Greet user
    console.log("Hello, " + name + "!");
}
hello("World");
                

Minified Result:

function hello(n){console.log("Hello, "+n+"!")}hello("World");
                

Notice how all comments, extra spaces, and line breaks are removed in the minified version!
