JavaScript Minifier

Description & Example

JavaScript minification is the process of removing all unnecessary characters from your code—such as spaces, line breaks, and comments—without altering its functionality. This practice reduces the overall file size, which in turn can speed up page load times and lower bandwidth usage.

This tool takes your JavaScript code as input and minifies it using a proven algorithm. In addition to providing you with the compact version of your code, it displays detailed statistics so you can see exactly how much size has been saved. The statistics include the original size in bytes, the minified size, and the percentage reduction.

For example, if you input the following JavaScript:

function greet(name) {
console.log("Hello, " + name + "!"); // Output a greeting
}

greet("World");

The minifier might output:

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

Along with the minified code, you will see a statistics panel showing:

Original Size: The size of your JavaScript code before minification.
Minified Size: The size after minification.
Reduction: The percentage decrease in size, reflecting the efficiency of the minification process.

This tool is particularly useful for web developers and programmers who need to optimize their scripts for production. By providing clear before-and-after size statistics, it helps you understand the benefits of minification in terms of improved website performance and faster load times.
