Minify your JavaScript code with our free JS Minifier. Remove whitespace, comments, and formatting to reduce file size and load your site faster.
JavaScript is at the heart of modern websites and web applications — powering everything from interactivity to animations to data handling. But uncompressed JavaScript can slow down your site and increase load times unnecessarily.
The JS Minifier helps you shrink your JavaScript code by removing unnecessary characters such as whitespace, comments, and line breaks. The result is a smaller file that performs the same way — but loads significantly faster.
A JS Minifier compresses your JavaScript code by eliminating characters that are not required for the code to function, including:
The logic and behavior of your script remain unchanged, but the file becomes smaller and more efficient.
When performance matters — and it always does — every byte counts. Minifying JavaScript:
Our JS Minifier makes this process easy, free, and instant.
Whether you're prepping a simple function or a complete app, this tool helps you slim down your JS fast.
Original JS:
javascript
// This is a comment function greet(name) { console.log("Hello, " + name); }
Minified Output:
javascript
function greet(n){console.log("Hello, "+n);}
The same result — just leaner and faster.
Fast websites retain users, rank better in search engines, and deliver a smoother user experience. With the JS Minifier, you can compress your JavaScript for optimal performance — with zero compromise on functionality.
