Great - super fast and fixed the problem perfectly

Came here from one of the big apps which could not handle basic things and seemed overwhelmed by the Shopify checkout integration. It was a great app when they offered all features for free... and even as they started charging. However, we've updated our rating as the functionality is really not up-to-scratch compared to the rapidly climbing prices... For example the merchant can't edit subscriptions, only the customer can, and there were all sorts of technical issues we had that the customer support team avoided helping with...

Fast and does what it says. This app isn't really concerned with the SEO aspects of images, but doesn't claim to be. Instead it compresses images quickly and effectively. Made an impact.
