Getting More from ExactDN
The default behavior of ExactDN is to use your existing images, compress them losslessly, and only resize when necessary, but it can do much more than that!
Important: For all of these options, make sure that you insert the option above where it says to stop editing. There will always be a line in your wp-config.php that says something like "That's all, stop editing!". Anything below that line will not work properly.
ExactDN can use either Pixel Perfect or Premium compression to make sure your images are packed efficiently. Premium compression averages about 5x the savings of Pixel Perfect mode. Enable premium mode in the ExactDN settings, or add this line to your wp-config.php
define( 'EXACTDN_LOSSY', true );
You can also change the default quality level by setting EXACTDN_LOSSY to a number from 60-90 instead of just "true".
WebP is a newer image format from Google that lets you gain additional savings on your images with minimal quality loss. To enable WebP support with ExactDN, simply enable JS (Alternative) WebP Rewriting, and the plugin will take care of the rest.
Resizing for Better Quality
If you aren't satisfied with the quality of the "resizes" that WordPress generates, you can tell ExactDN to re-resize all images on-demand, so that the resized versions will use the superior GraphicsMagick library, and you can also adjust the image quality on the Advanced EWWW IO settings (don't go higher than 90 though, that's just silly). To allow ExactDN to override existing resizes, you will simply need to add this line to your wp-config.php file:
define( 'EXACTDN_RESIZE_EXISTING', true );
Going Beyond Images (Include All Resources)
This option is enabled by default and tells ExactDN to rewrite urls for all content in the wp-includes (core WP content) and wp-content (user-generated content) folders. If you need to disable it, you can toggle it in the ExactDN settings, or add the line below and set it to false in your wp-config.php:
define( 'EXACTDN_ALL_THE_THINGS', true );
