Jpeg is tricky. The biggest thing that affects the size of the resultant file is the Quality factor. This can be changed when the file is saved to compare the visual image versus the size. This is why JPG is considered a lossy format. Each time it is saved a new image is generated from the displayed view. It is not really a copy. It is fresh conversion of the displayed image.
