Movavi Audio Suite offers you the possibility to convert your .cda files to .mp3 files. Install this application and after the installing process is ready, open its .exe files. In its interface you will find a button that says "Rip CD". Enter there, select your CD and output file and press "Convert". Also you need to know that this application was released in a shareware version, therefore, it has some limitations. For a full featured application I recommend you to buy it.
