ExactDN with the EWWW IO API (Cloud)
Some have asked the question (or something similar): If I use ExactDN, do I need to keep optimizing my images with EWWW IO? In particular, folks have wondered if they need to use the API on their images once they activate ExactDN.
The answer is "yes" but it's a bit more complicated than that.
ExactDN and Compression
If you read the Intro to ExactDN article, you may have noticed that ExactDN compresses every image that passes through it. Theoretically, that is EVERY image on your site, but again, some themes and plugins may do clever things that bypass ExactDN. Further, the compression used on ExactDN is the same as our Maximum Lossless setting, unless you enable ExactDN's lossy mode.
If you prefer our Maximum Lossy setting (like I do), then you should still be compressing your images using the API.
ExactDN vs. the API
In short, the recommended settings are to continue using the API to compress images with Maximum Lossy mode. ExactDN will take care of lossless compression for any images that pass through it and ensure no images goes unoptimized.
