So long as you measure in pixels, the DPI is irrelevant for screen, only
appropriate for print.

For the sake of proper design etiquette, it's a good practice to change
the DPI to 72dpi for screen, even though there isn't a difference in Kb.
So in Photoshop's Image Resize, first change the DPI from 300 to 72 (and
you'll see the W/H dimensions change if you have resampling checked), and
then adjust the W/H pixel settings.
