    This project’s goal is to reduce the size of JPEG files without reducing quality or compatibility with the vast majority of the world’s deployed decoders.

    The idea is to reduce transfer times for JPEGs on the Web, thus reducing page load times.

    ‘mozjpeg’ is not intended to be a general JPEG library replacement. It makes tradeoffs that are intended to benefit Web use cases and focuses solely on improving encoding. It is best used as part of a Web encoding workflow. For a general JPEG library (e.g. your system libjpeg), especially if you care about decoding, we recommend libjpeg-turbo.

    Tested a few of my jpeg images with mozjpeg (using 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.
