WP-Optimize now offers automatic conversion of JPG and PNG images to the WebP format during image compression.
To configure automatic WebP conversion, navigate to WP Admin -> WP-Optimize -> Images. You’ll find the WebP option under the Image Compression tab.
The WebP serving method (either htaccess redirection or AlterHTML) is auto-detected and applied by default. However, if you need to choose a specific method, you can enforce the use of the AlterHTML method by hooking into the wpo_force_webp_serve_using_altered_html filter. For example:
add_filter(‘wpo_force_webp_serve_using_altered_html’, ‘__return_true’);

The “backup original images” option preserves original (uncompressed) copies of your images with this setting enabled. This will nearly double the size of your uploads folder but provides a simple backup solution for your original media files. You can turn this off if you want to save space.

There may be a slight loss of image quality, but in most cases the quality loss is so tiny, it can’t even be noticed. Once your images are converted to a smaller file size, you will of course lose some of the data from the original file and the more you compress it, the more degradation occurs. One of the biggest reasons why we use lossy compression is that it maintains better image quality compared to lossless compression, while still giving a significantly reduced file size.
