I think you don't want -resample, but -density:

# density given in dpi
convert pic.jpg -density 72 pic-out.jpg

convert -density keeps the pixel size and changes the display size by
setting the density metadata.
convert -resample keeps the display size and changes the pixel size by
resampling at a certain density. (This explains why the picture
remained the same too-large size when you resampled at 72 and 300
dpi.)

Because you want to change the display size (and also because
resampling is a lossy process), I think you want -density.

As for the density value you want to use:
Your picture is 547px wide, so if you want it to display it 3 inches
wide you should set its density metadata to 547/3 = 183 dpi.

Does this work?
All the best,
Sietse
