The actor portrays the Apple co-founder in the upcoming biopic jOBS, which recently premiered at the Sundance Film Festival.
The picture features Jobs as he appeared later in life, with Kutcher unrecognisable with grey, thinning hair, glasses and a beard.
Kutcher accompanied the post with the message: "Thank you Sundance for the support of jOBS."
The film received a mixed reception from critics at Sundance, with many praising Kutcher's performance but criticising the film for being "mediocre" and "overblown".
Kutcher also revealed that the strict 'fruitarian' diet he went on for the role resulted in him being admitted to hospital.
