How to Minimize the Javascript file using an online tool?
JSCompress is a JavaScript compressor that allows you to compress and minify all of your JS files by up to 80% of their original size online. Copy and paste your code, or upload and merge several files before compressing. For all JavaScript minification and compression, we utilize UglifyJS 3 and babel-minify.
There are several reasons why you should compress your JavaScript files:
Users will benefit from faster download times.
Your website's bandwidth use has been reduced.
When you combine many JavaScript files into one compressed file, you reduce the amount of HTTP requests on your server, decreasing server load and allowing more users to view your website.
Comments and whitespace are not required for JavaScript execution; removing them reduces file size and speeds up script performance.
