What Does Minification Mean?

Minification is the process of removing superfluous characters from source code without affecting functionality. This saves time and bandwidth by making copying and pasting much simpler. If you are using JavaScript on your site, you should be using this too. 

This tool eliminates any line breaks or white space to speed up data transfer and make your site load faster. Additionally, it aids in shrinking the overall size of website files that use JavaScript.

In summary, the term "minification" means "to shorten or compress code." Our JavaScript minifiers make your code smaller by removing unnecessary characters like newlines, whitespace, semicolons, etc. They also rename variables to single letters if they are not being used.
