Try the following. It convert

#!/usr/local/bin/zsh
# $1 is the file or pattern to convert
for OLDNAME in $1; do
  BASE=`basename $OLDNAME .gif`
  NEWNAME=$BASE.$2
  mv $OLDNAME $NEWNAME
  echo $OLDNAME converted to $NEWNAME.
done

Name it "convert" and then use it like 
"convert list-of-file-to-convert new extension" for example "convert *.gif GIF"
