File size

Hello everyone, I have a question: What makes one image a larger file than another? Making backgrounds, I get one image at 2-3 Mb and another at say 7, but there are the same number of pixels and the same color management settings, and the same file format (e.g. both jpegs at 2400x2400 pixels at 8 bits/color). I find that resampling or applying a median filter can reduce size and many filters can increase it, but I have no idea why. I wan to fit as many as possible into as little disk space as possible. I would appreciate your ideas.
Many thanks,
Jennifer
