If you are looking to reduce the size using coding itself  you can follow this code in php    lt  php  function compress  source   destination   quality          info   getimagesize  source        if   info  mime       image jpeg             image   imagecreatefromjpeg  source        elseif   info  mime       image gif             image   imagecreatefromgif  source        elseif   info  mime       image png             image   imagecreatefrompng  source        imagejpeg  image   destination   quality        return  destination      source img    source jpg    destination img    destination  jpg     d   compress  source img   destination img  90     gt       d   compress  source img   destination img  90     This is just a php function that passes the source image   i e    source img    destination image    destination img   and quality for the image that will take to compress   i e   90      info   getimagesize  source     The getimagesize   function is used to find the size of any given image file and return the dimensions along with the file type

You can resize and then use imagejpeg    Don t pass 100 as the quality for imagejpeg   - anything over 90 is generally overkill and just gets you a bigger JPEG  For a thumbnail  try 75 and work downwards until the quality size tradeoff is acceptable   imagejpeg  tn   save  75
