What is minification (and how it speeds up your site)?

Minification is the process of removing unnecessary characters — spaces, line breaks, comments — from your website's code (CSS and JavaScript) without changing what it does. Smaller files download faster.

Why it helps

• •Smaller files mean faster load times.
• •Less data for visitors, especially on mobile.
• •It's a free, no-downside performance win.

It should be automatic

You should never have to minify by hand — a modern build process does it for you when the site is deployed. It's one of many small optimizations that add up to a fast site.
