Convert ASF to WMA — Free Online Converter

WMA (Windows Media Audio) is the audio codec commonly found inside ASF containers, but WMA can also exist as a standalone .wma file. Converting ASF to WMA is primarily an extraction operation — pulling the WMA audio stream out of the ASF video container into its own dedicated audio file. This is useful when the ASF contains both video and audio, but you only need the audio track.

ASF is a container designed for streaming video and audio together. If you only want the audio (a soundtrack, voiceover, or music track), extracting it to a standalone WMA file saves significant disk space by discarding the video data. The resulting WMA file plays in Windows Media Player, Groove Music, and other Windows audio applications without video player overhead.
