Minify JS to reduce file size or beautify compressed code for readability
Minifying JavaScript removes comments, unnecessary whitespace, and redundant semicolons to shrink file size and speed up page loading. This free online JavaScript minifier processes your code instantly in the browser and displays detailed compression statistics showing original size, output size, and percentage saved. When you need to read or debug minified code, the beautifier reformats it with proper indentation and line breaks.
You can paste code directly into the editor, upload a .js file, or drag and drop it onto the input panel. The tool handles ES6+ syntax including template literals, arrow functions, and destructuring. After processing, copy the result to your clipboard or download it as a .min.js file.
All minification and formatting happens client-side. No JavaScript is uploaded to any server, keeping your source code completely private. Built for web developers, this tool is a quick alternative to build-tool pipelines when you need to compress a single file.
