Why Compress JPEGs?
While JPEGs are already compressed, cameras and phones often save them at 100% quality. The difference between 100% quality (a 6MB file) and 85% quality (a 800KB file) is virtually invisible to the human eye, but it makes a massive difference to Google. Compressing your JPEGs before uploading them to your blog or e-commerce site is the easiest way to improve your Core Web Vitals and SEO rankings.
