title: Reduce image file size without resize and quality lose
body: <p>In a site i am daily uploading around 100+ images that have taken from digital cameras, a single image file have an average file size of around 3MB. It needs high amount of disk space in server. If i can reduce the average size below 1MB i can upload more images in the current space.
  I have tried many online image optimizers, but all of them can't helped me to reduce below at least 1.5MB.</p>
