 * Tested a few of my jpeg images with mozjpeg (using [http://mozjpeg.codelove.de/](http://mozjpeg.codelove.de/)
   losslessly) after i ran them through EWWW/jpegtran and I was able to save a few
   KB in every picture I tested. Didn’t save that much, but still something.

 * The EWWW IO Cloud API switched over to mozjpeg a few months ago, but the free
   version of EWWW IO includes the stock jpegtran from the IJG. As you’ve noted,
   it does save a few KB on most images, which is exactly what I found in my testing
   earlier this year. Version 3 of mozjpeg has even shown improvements over what
   was possible last year with version 2 where the results were better than the 
   IJG only about 60-70% of the time.
 * You are free to install it on your own server if you know how to compile things,
   and if you have the ability to install software on your server. However, I’ve
   been unable to get a static (portable) binary for mozjpeg that would run on linux,
   so I’ve stuck with the IJG version for the time being. If you like, you could
   also signup for the EWWW API, but I don’t know that those few KB are compelling
   enough to be worth the money, but that’s totally up to you.
