Having recently shrunk several images here, the command that does somewhat of 
what you're looking for is:

VBoxManage modifyvdi your.vdi compact

I quantified the above with "somewhat" because it takes some preparation to get 
good results.  The key thing is to make sure that the slack space on your image 
is zeroed out.  There are many howto's to explain how to do this with Windows 
systems, but I got good results by making an all-zero vdi target and 
subsequently (a) rsync'ing the root filesystem over, (b) installing grub to the 
new MBR (b2) [optional] boot to verify it works, and then (c) compacting.
