Jampack is a post-processing tool for static websites that optimizes user experience and Core Web Vitals scores by automatically enhancing images (making them responsive with modern formats like WebP and AVIF), inlining critical CSS, compressing assets, and implementing lazy loading for below-the-fold content. It's designed for developers using static site generators who want to improve their website's performance without changing their build process or learning a new framework.
