Indentation

Beautified JavaScript

JavaScript Beautifier / Minifier is a free online developer tool to beautify messed up JavaScript code with your preferred indentation or minify JavaScript code to be compact for production.

This tool is split into two modes: JavaScript Beautifier and JavaScript Minifier.

You can either browse a JavaScript file locally from your device, fetch a JavaScript file from a URL, or enter JavaScript code manually.

JavaScript Beautifier - Beautifies messed up JavaScript code by formatting it to be human-friendly and more readable with your preferred indentation level; e.g. space or tab. Useful for development purposes.

JavaScript Minifier - Minifies JavaScript code for production use. This mode removes all the unnecessary whitespace characters and comments, and mangles variable names.

Your JavaScript code will be optimized to be more compact, performant, and production ready, and your website load time will significantly be reduced.

When you're done, you can either copy the result to your clipboard using the copy button or download it as a JavaScript file to your device using the download button.
