Question about withdraw in dollars to a euro bank

I will do a withdraw from the Fiverr website which the currency there is USD to my Payoneer account soon.
The doubt is after I receive my funds in my Payoneer account balance in US Dollars , I want to withdraw my money to my bank account in Portugal in Euros.
If my balance will be in Dollars, how can I exchange from USD to Euros in order to be possible to withdraw my money to my Portuguese bank account?
