Smallest possible? Kenny code converters
(m=0, p=1, f=2; so 'A' encodes as 'Mmm')
e.g.
"What's up, Doc?"
encodes as
"Fppmfpmmmfmp'fmm fmfpfm, Mpmppfmmf?"

Encoder 73 bytes:

Both use DOS Int 21 for redirection; e.g.
Enken<plaintxt.txt>kencode.txt
Deken<kencode.txt

Asm programs assume bx=0,al=0 at start
Size limit of 15k of plain txt.
Capitalisation catered for.
Nonalpha chars 'encoded' asis, and similarly any
non-kennycode chars in the decode stream left asis.
But GIGO rules still apply!

Bah, and indeed Humbug.

UFOs are for real: the Air Force doesn't exist.
