The short answer
Add your WMA files, choose MP3 in the Audio profiles, review Audio settings and click Convert. The app converts ordinary supported audio; it does not remove DRM from protected WMA purchases.
Check whether the WMA is accessible
Try playing the source before converting it. Some older WMA downloads use a protection system tied to the original provider. If a protected file will not open, choosing MP3 does not decrypt it. See the protected-WMA explanation for that distinction.
Add the WMA batch and choose MP3
Choose Add audio in Free MP3 WMA OGG Converter. Check the selected files in the queue, select an MP3 output profile and review Audio settings. Keep the existing sample rate and channel layout unless your destination needs something different.
MP3 re-encodes the audio. Raising the output bitrate cannot restore information already discarded from a lossy WMA. Keep the source for any later conversion.
Save separate MP3 files
Choose Save to and an output folder. Leave Merge files off for one MP3 per input, then choose Convert. Check the resulting filenames, duration and sound in your intended player.
If an output is unexpectedly large, review the bitrate and duration. If it is silent or incomplete, confirm the original plays correctly before retrying. For other outputs, use the audio format comparison.
