For example my image is 300DPI, and if i downscale it, does that change? Because for a contest i compulsorily need 300 DPI but the file size should be less than 10mb... pls help

dpi alone doesn't affect the image size and is purely a metadata. it is used only when you decide to print an image. JPEG quality and DPI are two different things
