What quality is the right one?


Often images can be compressed more for viewing on a full HD Screen (TV or PC), resulting in a smaller file without differences for the human eye.


 

Quality is too high

 

Viewers can't see any difference in the quality.
Files take up much space, copying and loading is slower.
