📸 What Is Kraken.io Image Optimizer?
Kraken.io Image Optimizer is a WordPress plugin that connects your website to the Kraken.io image optimization API. Instead of compressing images locally on your server, Kraken performs cloud-based lossy or lossless compression, drastically reducing image sizes while maintaining high visual quality.
This is especially helpful for websites with lots of images — such as blogs, portfolios, galleries, and eCommerce stores — where image size directly affects load time and user engagement.
