Sirv is fantastic! I have a lot of images on my website, which resulted in slow site speeds, even with a CDN. I love Sirv because they offer a CDN service but also dynamically resize and optimize images based on the user’s browser/device. It has meant HUGE speed improvements on my website. In addition, the WordPress plugin works a treat and the support team is fast. Highly recommended!
We got a huge speed boost in loading time on GTmetrix, Pingdom FPT, Google Pagespeed Insights and Webpagetest when we enabled Sirv on our WooCommerce site. It resizes our big images and solved our theme issue of one image size everywhere. I strongly recommend this plugin to every body who desires to have fast loading images. I will be implementing this plugin in all of my sites.
We use Sirv for many of our clients when designing their new sites/apps. The dynamic image resizing, optimisation and zoom benefit different types of business for different reasons. We particularly use it for e-commerce sites, so zoom into images. Also a large property website that requires hi-res optimised images.
