Why Minify JavaScript?
Minification reduces the size of your script files, leading to faster download times for your users. Paste plain JavaScript, select Minify JS, then copy the result. A syntax error is shown instead of generating a broken output. Smaller source files can reduce transfer size, but minification alone does not guarantee better rankings or a faster page.
