A former winner of the BBC’s Young Composer of the Year took images of women from social media and uploaded them to pornographic websites, a court heard.
Woolf asked users to attach the women’s faces to images of porn actresses, before posting the doctored pictures on adult websites.
At Thames magistrates court, Woolf, from Cambridge, admitted 15 charges of sending messages that were grossly offensive or of an indecent, obscene or menacing nature over a public electronic communications network.
On Monday he was handed a 20-week prison sentence, suspended for two years, and ordered to pay £100 in compensation to each of the victims.
Woolf shot to prominence in 2012 when he won the prestigious BBC composing contest, and he went on to study at Cambridge University and the Royal Academy of Music.
The CPS said none of the original images of the woman Woolf targeted were pornographic or indecent before they had been doctored.
The composer committed all the offences from his home in Cambridge between June 2020 and April this year.
The crimes came to light when one of the victims received an anonymous tip-off in January, saying her image had been posted on Reddit.
She was sent a further message in March, revealing that her doctored image was on a porn site and Woolf was behind the post.
“Woolf’s behaviour is severely depraved and reprehensible ... and has had a drastic impact on his victims”, said Varinder Hayre, a district crown prosecutor at the CPS.
“We will always look to prosecute the sexual exploitation of victims and this prosecution is a clear message that this morally repugnant action will not be tolerated.
“I am especially pleased that Woolf has to delete all these pictures from his devices and will not be able to contact his victims ever again.”
Woolf was ordered by magistrates to attend 40 days of rehab, attend 40 sessions of a sex offender programme, and carry out 150 hours of community service.
He must also pay £213 in court costs and fees, and is banned under an indefinite restraining order from contacting the victims.
