Bad image quality dawn theme

[pauda]

Hey friends, 

The Shopify support team is keeping me alone with this problem so maybe you can help me. 
The quality of the image inside of my new store (Not finished) is so bad and i dont know why. I have the right format and i dont know what to do. Can someone help me here?

Which images are you having issues with? They appear more or less fine to me but maybe I'm not looking at the right area
