Resizing will make the file smaller. Fewer pixels - smaller file.
If you want further compression that what you get from plain resizing, you need to use less data per pixel, i.e. adjust data quality.
For a jpeg, you adjust the compression ratio for the jpeg when you saving file.
File | Save As, click on More, select a higher JPEG compression ratio
Can't remember if you express compression ration in MSPM as percent (select e.g. 91 for 91%), or in scale factor (select e.g. 2). Experiment.
Give the file a new name, so you keep the original, in case you are not happy with result.
