The MP3 audio file extension is the king of all music formats. Playable on nearly every portable music device, the MP3 and its titular "MP3 Player" are a part of the lexicon. However, in order to get the files to work in certain specialized applications, one may need to convert MP3s into a different format. The WAV format is an audio format with adjustable bit rates and sampling rates, while the WMA extension is often used for playing songs on the Web.
Access mediaconverter.org in your favorite browser.
Press "Upload a file" on the home page and pick out the MP3 you want to convert. The file's name appears under "Selected Files."
Select "WAV" or "WMA" as the output extension. Click "Start" to kick off the conversion.
Click on the link that appears after the conversion is done. This commences the file download to your hard drive.

Click on "Choose File" button and search through your hard drive for the MP3 you want to alter.
Select "WAV" or "WMA" in the dropdown menu, then enter your email address.
