I created a backup of flash card, using: dd bs=4M if=/dev/mmcblk0 of=backup.img

Now, trying to restore that back to the same card with Etcher, I'm told the image is bigger than the card, and I need 300+Mb of more space.

Should I be creating the image a different way? Is there a work-around to restoring the image? If it matters, I'm trying to maintain all of the needed partitions for a RaspberryPi. I'm new at this, so any guidance would be great (including if there's a more appropriate Exchange to ask).

Since my question was focused in particular on a RPi .img file, there is a utility, PiShrink https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh for this very task.
