When to Convert
Common scenarios where this conversion is useful
Import browser-recorded audio into Windows Media Player
WebM files recorded in a browser will not open in Windows Media Player, which does not support the WebM format natively. Convert to WMA to import the audio into your Windows Media Player library seamlessly.
Create audio for Windows-based corporate environments
Many corporate Windows environments use Windows Media Player for audio distribution. Convert web video recordings to WMA to share training or meeting audio in a format that works without additional software on managed Windows machines.
Play web video audio on Xbox
Xbox consoles support WMA for media playback from USB drives or network shares. Convert WebM video audio to WMA to listen to it through your Xbox home theater setup without a PC.
Prepare audio for older Windows Mobile or CE devices
Legacy Windows phones and portable media players do not support WebM. Converting to WMA provides a widely compatible audio format that works on most Windows-era devices from the 2000s and 2010s.
Convert web meeting audio to WMA for Outlook sharing
WebM files are not easily shared via Outlook email. Convert the audio from a web meeting or webinar WebM recording to WMA for an easily attachable Windows-native audio file.

Frequently Asked Questions
Windows Media Player does not include a WebM codec by default. Converting your WebM audio to WMA produces a file that Windows Media Player can open and manage natively without any codec installation.
Yes. Converting between lossy codecs (Vorbis or Opus to WMA) involves re-encoding. At high bitrates the quality difference is imperceptible, but each re-encoding step introduces a small loss compared to the source.
FFmpeg encodes WMA at a high quality bitrate by default, typically 192 kbps. This is suitable for music, speech, and general audio content at excellent perceptual quality.
WMA support is limited outside Windows. Some Android devices and the VLC app on both Android and iOS support WMA. For cross-platform use, MP3 or AAC are more reliable choices.
Yes. Xbox consoles support WMA playback from USB drives, local network shares, or OneDrive. Convert your WebM audio to WMA and copy it to a FAT32-formatted USB drive to play it on your Xbox.
WMA supports Windows Media metadata including title, artist, album, genre, track number, and cover art. These tags can be set or edited in Windows Media Player or tools like Mp3tag.
