Well If your using photoshop, the best thing to do is when you are saving your 1080P images to upload, go to Save For Web (Legacy) instead of Save As Because
What it will do is slightly compress the image so, it is not as large and I recommend doing this with other things aswell! :)

(This is mainly to help Photoshop users, Not Paint, but I will research a way! ;))
