See more reviews here Overall: We mainly wanted to resolve the image related issues/opportunities mentioned in our Google web vitals report. The report suggested to properly size the images and serve images in next gen formats. So we look out for an image CDN and imagengine worked perfectly for us. Pros: Automatically converted the jpg images on our website to webp. This solved the issue of images in next gen formats mentioned on our Google pagespeed insight score. Optimized the image payload by 78%. So no complaints!
