EWWW cloud and JPEGMini resizing question

    If I understand correctly, EWWW cloud use JPEGmini to optimize images. I was wondering how this works for the resized (thumbnail) images specifically. Does EWWW first let WordPress resize image to create the thumbnails before optimizing them? Or is the resizing performed by EWWW Cloud itself from the original image, and then optimized with JPEGmini? Or does JPEGmini handle everything, including the resizing?

    The reason I ask is because I’ve read that you can replace the standard GD library used by WordPress with ImageMagick, and I’m not sure if that’s actually useful when using EWWW.

    EWWW does not create the resizes itself, it lets WordPress handle that part, and then optimizes them afterwards. So yes, if you install imagemagick on your server, WP will use that instead of GD. You could even confirm that Imagemagick is being used by turning on debugging, and checking the file debug.log in the ewww-image-optimize folder. Upload an image, and you’ll see a section in there where it lists the WP_Image_Editor implementations that are active, and you should see the Imagemagick one listed.

    Thanks for the answer. I’m guessing this means that the resized images are actually compressed twice, once by WordPress (since it also uses JPG) and then by JPEGmini?

    Yes, although WordPress does it at quality 90 by default, so you shouldn’t really see any loss there.

    And to be completely clear, JPEGmini is not currently used by default. The default mode is lossless, so you do not see ANY loss, because there isn’t any. If you enable lossy mode, then EWWW IO uses TinyJPG by default, and the next version will have an option to use Faster lossy compression (JPEGmini). The switch to TinyJPG hasn’t been fully documented yet, but that will happen within the week.
