You can individually set the compression quality of the resized image that is automatically generated when you upload the image to the WP media library.

Setting the optimum compression quality level helps ensure image quality and speed up page display.
The quality level can be examined while checking in real time.

This plugin will automatically generate the same quality and more compressed WebP if your server supports WebP.
And if user’s browser supports WebP, deliver automatically WebP instead of JPEG or PNG. (No need to rewrite the URL of the tag)
It contributes to improving CWV (Core Web Vitals).
