Kraken Image Optimizer Module

If you have read my blog before you know that I am all about optimizing sites for speed. For a couple of years now I have used to optimize images on the sites that we optimize. The real hassle with it is trying to optimize all of the images, there is just no good way to do it. You cannot upload a zip with multiple directories to Kraken and have the images optimized. You are really just limited to optimizing the main images used in the site such as the template images and the slider images.


But this module changes that

This module is built by the same company that built the Smushit Optimizer module, PresTeamShop. But it has a different fit than the Smushit module. Smushit is a free image optimization service offered by Yahoo. But Kraken is a paid service. Why chose something that is paid versus a free service? The optimization quality is the reason. Kraken can optimize the same image with a 20-30% reduction than what Smushit can do, that is the main reason we switched over to using Kraken.


How does the module work?

The module installs easy enough, the only real qualm I have with it is it requires itself to be registered before you can use it. But once you get through that, you need to enter your Kraken API key. Remember, Kraken is a paid service, it has plans starting at $9 a month and is well worth it if you are trying to maintain a fast website. The main module area looks like the image below.

From this interface you can choose what images you want to optimize, category, product, manufacturer, ect. Also you can optimize images by directory as well. This feature is super handy for optimizing theme related images, slider images, and custom block images as well. You can see the interface below for how it handles optimizing by directory.

The interface is very easy to use and laid out in the most logical manner that it can be laid out. The functionality of the module works perfect as well. I optimized over 1000 images with the module and did not have one issue.
