I still see images that are 2MB or more in size or large in dimensions in some cases, why is that?

The reason for that is that your image dimensions are huge. Unfortunately, our tool does not optimize for the dimensions (or scale them) as a tool wouldn't know where all are those images being used. For eg, whether on a particular page the image should be 300px or 1200px - our tool can't figure that out. So we are only optimising for file size.

If you wish to further optimize the images, please feel free to write to us on litepics@niswey.com and we will provide that as a service.
