Hello, There are many software's that are available on free for reducing picture sizes. One very commonly that I use is shrinkpictures.com you can also try it by yourself. Also, if you need some one professional to do such kind of job then contact Isabella, I have found her profile on website while looking for some professional for photo restoration process. I have a pic of my Father and it is almost 34 years old image, it is too much blur even can't see it clearly. So, I have contacted her nd she is really good.
