Resized Images are more KB than the original.

It is easy to fix by adjusting ImageMagick Engines’s quality settings.

There is a play between ImageMagick Engine’s quality settings in relation to the quality setting of my original jpeg. Especially since one of my resized images is the same px by px size.

This forum touches on the idea: http://www.imagemagick.org/discourse-server/viewtopic.php?t=22696

I ran some test and I can run up to 100 quality with my smaller outputs but need 80-85 for the largest output. But there isn’t a one size fits all with the settings. Everyone has different resize outputs and quality inputs. So, run some test before regenerating your whole library.
