The code behind your pages (CSS, JavaScript) can be slimmed down automatically.

Minify

Minification strips out unnecessary spaces and characters from the code: same features, lighter files.

Bundle and defer

• Bundling several files into one reduces the number of requests.
• Deferring non-essential JavaScript speeds up the initial display.

Most caching plugins offer these options with a single click.

Be careful: test the site after switching them on — overly aggressive minification can break a layout. Enable the options step by step.
