This currency preference selection may be presented to you in various forms, including setting the currency of your card, a choice of which currency is used for the transaction, whether PayPal or your card issuer performs the conversion, or which conversion rate is used for the transaction, among others. If your card issuer converts the currency, your card issuer will determine the currency conversion rate and the fees they may charge. PayPal will always perform the conversion for transactions where you use your existing balance in your PayPal account or your linked bank account is the payment method.
