Capacity Reduction Techniques in WEBP Conversion of PNG in EWWW

EWWW Image Optimizer is a WordPress plugin that optimizes images. By default, this plugin converts PNG images to WEBP with lossless (lossless compression), but while the image quality remains high, the size reduction effect is limited.

To achieve a more significant reduction, add the following code to wp-config.php.

define( 'EWWW_IMAGE_OPTIMIZER_LOSSY_PNG2WEBP', true );

This setting changes the PNG to WEBP conversion to lossy (lossless compression). Lossy compression slightly reduces the quality of the image, but greatly increases the size reduction effect.
