Jim Birdsall is right.  Look at the following examples.  Consider first that
a binary files has statistically 50% bytes with leading zeroes and 50%
bytes with leading ones (varies from file to file, but statistaclly
right).  That means that transferring a binary file on a 7 bit ASCII
connection will cause 50% of the bytes to be quoted.  Equivalent of
increasing the file size by 50%.  UUENCODEing is a 3 byte-to-4 byte encoding
of your binary text.  It increases your file size by 33.3% (regardless of
the percentage of bytes beginning with 1's or 0's!).  Obviously transferring
a binary file over an 8-bit line has no penalty (0% file growth!).
