About MinifyJS

MinifyJS is an online JavaScript compressor that allows you to compress and minify all of your JS files by up to 80% of their original size. Copy and paste your code or you can upload and combine multiple files and then compress. We use UglifyJS 3 and babel-minify for all JavaScript minification and compression.

Why You Should Compress JavaScript

There are a number of reasons why compressing your JavaScript files is a good idea:

Quicker download times for your users.
Reduced bandwidth consumption of your website.
Reduced number of HTTP requests on your server when combining many JavaScript files into one compressed file, thus reducing the server load and allowing more visitors to access your website.
Comments and whitespace are not needed for JavaScript execution; Removing them will reduce file size and speed up script execution times.
