Image cropper works by optimising the image, pulling it in and caching it. Each time the editor selects a crop, the system will use image processor to optimise it and the cache it for use.
Often, rather than cropping several versions of the same image, we use one copy and then use front end scripts to resize for each device so that the editor doesn't need to select one for each device, based on screen sizes.

Image Cropper - Filesize
I was recently asked if the Image Cropper reduces the filesize of the image when displaying in mobile.
My assumption was that it didn't, it just adjusted the aspect ration/size of the image.
My reason for asking is that the person concerned wants the same image created in different sizes for delivery on the appropriate device.

Thanks Emma. Does this ensure both quality and data download on mobile devices are optimised?
