Through hands-on experiments comparing JPEG and AVIF codecs, the article demonstrates how to evaluate compression methods using metrics like SSIM and neural networks. It covers codec parameters, quality assessment challenges, and provides actionable recommendations including using MozJPEG, serving multiple formats with the picture element, implementing lazy loading, and leveraging cloud-based image processing services.
