All screenshots taken on a MBP 2015 (retina, default resolution) has a "resolution" of 144x144.
When we upload those images to forums, they are usually stored as 72 DPI, hence the actual image dimension is 4x larger, which is annoying if said forum doesn't give users control on image display size.
I want to resize these screenshots to 72 DPI, without increasing dimensions. I am aware that
sips could do this in batch, but wonder if there is a more user-friendly way?
