JavaScript Formatter, Minifier & Beautifier Explained

This online tool helps you clean up, format, and optimize your JavaScript code instantly. Whether you're working with messy, unformatted code or need to reduce file size for faster loading, this tool has you covered.

Format JS: Transforms compact or poorly indented JavaScript into a readable, well-structured format with proper indentation and line breaks, making it easier to understand and maintain.

Minify JS: Removes unnecessary characters from your JavaScript code, such as whitespace, newline characters, and comments, without changing its functionality. This reduces file size, leading to faster website loading times.

var x=1;function f(y){/*a comment*/return x+y;}f(2);

var x = 1; function f(y) { /* a comment */ return x + y; } f(2);

var x=1;function f(y){return x+y;}f(2);
