Well, but it fails (but returns exit status success) even if the file
is compressed (ex. gzipped) but the fipped file extension isn't .gz.
It will procuce an exact copy of the original.

This is a .tar.gz file:

-rw-r--r--    1 root     root          2736 Oct 21 16:32 foo.tar.bar

# zcat foo.tar.bar >foo.tar;echo $?
0

-rw-r--r--    1 root     root          2736 Oct 21 16:37 foo.tar
-rw-r--r--    1 root     root          2736 Oct 21 16:32 foo.tar.bar

Attemting to extract the archive will fail instead, with appropriate
exit status.
