Increase image size in kb without changing pixels using command prompt or bash

Most of the online application sites restrict the users to limit the photo or image size with certain specifications like color depth, resolution, file size etc. Compramising resolution will result in small image size which restrict applicants.users to upload unless an image file is of certain size.
