Size of img too large still..

Don't know if this will be seen but I've noticed that using a USB drive (256gb ) it makes an image that's 14gb, even though used space is only around 5gb.

I use another utility and it creates a 5.1gb image ( no compression) 

When I cloned by 32gb card it showd as a 5.5gb image.  But after restoring that image to aarver card and expanding the file system,  I now get 14gb 
Img.
