So I have been working with the Kraken.io Image optimization service for a couple projects, as previous blog posts might have indicated. And must say that not having to include, build, debug, maintain and host an image compression library is really a big deal when you sum it all up. I personally don’t like to waste time on non-core business processes. In addition, nowadays it’s often hard to justify the costs. There are so many problem specific hosted solutions available with great support, documentation, API’s etc.
