Should you convert WEBM to WMA?
Yes, when you only need the sound: a song from a music video, the audio of a lecture, or a voice recording to transcribe. The picture is left out and the soundtrack is saved as WMA.
WEBM is the web’s open video format, holding VP8, VP9 or AV1 video with Opus or Vorbis audio; WMA is the Windows Media audio format from the Windows XP era. Choose WMA only for an old Windows device; convert your WMA rips to MP3 or M4A to play them anywhere.

How to convert WEBM to WMA
- 01
Add your WEBM
Drop your WEBM video onto the box, or click to choose it. It is read from your disk and stays there.
- 02
Check the settings
The output is already set to WMA. Change the bitrate if you want to; the defaults suit most files.
- 03
Save the WMA
Press convert and save the WMA. Several files come back together as a ZIP.
What changes when WEBM becomes WMA
From Opus to WMA
WEBM soundtracks are usually Opus, so saving WMA is one more lossy step. 192 kbps suits music, 128 kbps is plenty for speech, and going above the original bitrate only makes the file bigger.
Video files without sound
Screen recordings and some exported clips have no audio track at all. The file is checked as soon as you add it, and you’ll be told before converting if there’s nothing to extract.
This page is put together from our notes on each format, choosing only what is true of WEBM and WMA, so every pairing states the same facts the same way. How these pages are made.
Why it doesn’t upload
Uploading a whole video to keep only its sound wastes time and data, and hands over the footage too. The audio track is read and saved right here, and the file never leaves your device.
How to check for yourselfWorth knowing
- About the WEBM. Browser screen recorders save WEBM, and the recording then fails to upload or attach almost everywhere else.
- About the WMA. WMA files bought from old online stores are often DRM-protected; no converter can open those.
- AVI, WMV, FLV and other older formats use the FFmpeg engine, a one-time 31 MB download.
Questions
Does extracting WMA from a WEBM lose quality?
The soundtrack is compressed again as WMA. At 192 kbps the difference from the original is inaudible for nearly everyone.
Can I get the audio from only part of the video?
Yes. Set a start and end time before converting, and only that section is saved as WMA.
