At TPTQ Arabic you can upgrade previously licensed fonts in other formats to OpenType. We will deduct the price of the fonts you have already paid for. For example, if you upgrade the PostScript version of Fedra Sans Book (for which you paid €60) to Fedra Sans Std Book (priced at €90) you will pay only €30 extra. Since we need to verify your previous order, please write to us directly with your upgrade requests.
