How do I convert a WMV video to an M4A audio file?

Upload your WMV file to LetsConvert, select M4A as the output format; the tool will extract the audio track from the WMV container and encode it to M4A (AAC or ALAC). You can adjust audio bitrate in settings, then click Convert and download the resulting .m4a file.

Why should I convert WMV to M4A instead of keeping the original file?

WMV is a video container that may be large and is optimized for Windows Media Player, while M4A is a pure audio format (MPEG-4 part 14) that uses more efficient AAC compression or lossless ALAC. Converting to M4A reduces file size by up to 50% and ensures playback on Apple devices, Android, and modern media players without codec issues.

What happens to the video track and audio quality when I convert WMV to M4A?

When converting WMV to M4A, the video stream is discarded because M4A is an audio-only container. The audio stream is extracted and transcoded to AAC or ALAC depending on your chosen bitrate—if you select lossless ALAC, the audio samples are preserved exactly; with AAC, the sampling rate is retained but compression may remove inaudible frequencies. Metadata like cover art and tags are copied, but video resolution and frames have no effect on the output.
