You can just download base.txz direct from the FreeBSD FTP servers. eg:

http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/12.1-RELEASE/base.txz

That's the same as goes into the release images.  Make the obvious 
substitutions for different CPU architectures or release versions.

To answer your actual question: try tar(1). It can read a lot of 
disk-image formats.  Not sure about the .img file, but it can certainly 
read .iso images.
