What the author says it does
Eliminate Render-blocking Javascript in above-the-fold content with Async Javascript.
Render-blocking Javascript prevents above-the-fold content on your page from being rendered until the javascript has finished loading. This can impact on your page speed and ultimately your ranking within search engines. It can also impact your user’s experience.
Async JavaScript gives you full control of which scripts to add an ‘async’ or ‘defer’ attribute to or to exclude to help increase the performance of your WordPress website.
The opening of the plugin's own description. The full text, installation notes and changelog are on its WordPress.org page.
Questions the author answers
Which browsers support the ‘async’ and ‘defer’ attributes
The ‘async’ attribute is new in HTML5. It is supported by the following browsers:
- Chrome
- IE 10 and higher
- Firefox 3.6 and higher
- Safari
- Opera
Where can I get help?
Async JavaScript is supported via the wordpress.org support forum.
Do you offer professional support/ configuration services?
We offer premium services for Async JavaScript and full web performance optimization services at https://autoptimize.com/
What about CSS?
As the name implies, Async JavaScript is built to enhance JavaScript loading only. Async JavaScript does not have any impact on CSS.
We recommend using the awesome Autoptimize plugin alongside Async JavaScript for CSS optimization.
I want out, how should I remove Async JavaScript?
- Disable the plugin
- Delete the plugin

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin. The author takes donations at their donate page.
