These are some awesome comparisons, @buddingphotographer! Very helpful.
So, to help @Mr.Quebec get a smaller file size, is there a way for him to reduce the actual pixel dimensions? His most recent upload is 4272px wide. This is why it’s difficult to get it below 2MB. Uploads really only need to be 800px wide, or 1600px wide if he wants to display full screen.
The Quality settings you have been discussing thus far does effect file size, but only slightly. Reduce the pixel dimensions and you’ll be on the road to solving this problem.
