In the world of web performance, every kilobyte counts. Large, uncompressed images are often the #1 culprit behind slow loading times, high bounce rates, and poor SEO rankings.
Enter —a brilliant, yet lesser-known, image compression tool developed by Google (specifically, the team behind Dropbox’s image optimization research). Unlike standard JPEG compressors that strip metadata or lower quality, Lepton uses a sophisticated predictive coding method to losslessly compress JPEGs by an average of 22% . descargar lepton optimizer gratis
