My Pi 4 came with a 16 GB card and I installed and configured the Pi (from
NOOBS) using this card. But I notice that there's only about 1.5 GB free -
83%.

If I make an image of the card using Win32 Disk Imager and copy the image
back to a 32 GB card, is there a way of making RaspiOS increase the size of
the / partition to use the full space on the card?

Or is there another, better disk imager tool to use for this?
