How can i compress my photos so they dont have as much memory?

Question

i've tried cropping images but how can i change it from say 600kb to 100kb without cropping it any further??????

Answer 1

Change the format to jpeg.

Answer 2

Photo's don't have memory but you can compress them by saving in a compressed file format such as JPG.  If they are already saved as JPG you can increase the compression to reduce the file size but the picture quality will suffer.

You could also resize the image.
