Jampack is a post-processing tool that optimizes static websites for the best user experience and Core Web Vitals scores. It is not a bundler or framework, but rather works with the output of Static Site Generators. Jampack can make images responsive with dimensions and multiple formats, optimize CDN images, and compress assets for faster loading. It also offers features like lazy-loading assets, inline critical CSS, prefetch links, and compressing various file types. Overall, Jampack streamlines the process of optimizing websites and enhancing performance. Some might find the renaming of external images controversial, but the tool is unique in its approach.
