JSCompress Tool 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.
