Massive reduce in sizeCons:
No video yet, batch conversion, other formats, fine-tuning
I can recommend ImageKit that I've been using for a couple of months (I guess I'm one of the first users). It makes slightly smaller images than Google's image optimiser without adding noticable visual noise. This is still an early product and I'm sure they going to support better the enterprise-y features such as signed repos, custom storage and distribution (Big Shots usually have their own CDN), batch processing and support for videos. Anyway, it is quite handy already, especially if you don't have a strong oppinion how the images need to be delivered / processed.Janos Feher has used this product for one month.
Price, simplicity to setup, support and real time transformationsCons:
No video support
The team was really supportive and their tool is great and simple to integrate on any e-commerce site. They support out of the box Magento, Wordpress and others.
