The short answer
Add the MP3, choose a WMA output profile, review Audio settings and convert to a new folder. Choose WMA because the destination requires it; converting an MP3 does not improve its original quality.
Check that WMA is the required output
Confirm the exact player or software requirement. WMA support varies by destination, and the common WMA output is different from WMA Lossless. Do not choose WMA merely because you expect every WMA file to be smaller or sound better than an MP3.
Select the WMA output profile
Open Free MP3 WMA OGG Converter, choose Add audio and add the MP3 files. Select WMA in the Audio profiles and open Audio settings. Use a bitrate, sample rate and channel layout accepted by the destination.
This is a lossy-to-lossy conversion when both the source and output use lossy encoding. Keep the MP3 originals and avoid a chain of repeated conversions.
Convert a sample before the whole batch
Choose a separate Save to folder and click Convert. Test the WMA on the actual player, including a longer section and the ending. If the device rejects it, check its supported profile and settings rather than changing the filename.
Leave Merge files off for separate outputs. If you need wider MP3 compatibility in the other direction, follow WMA to MP3.
