Excelente
Lo he usado y lo uso en varios sitios, principalmente para optimizar imagenes en sitios de noticias que muchas veces los editores por el "apuro" o por ignorancia, no editan las imagenes. Me resuelve problemas de carga y velocidad del sitio, ademas que la optimizacion ayuda en el SEO. Recomendado!!!!
