Quick answer: To extract WAV audio from WEBM video, add the WEBM file to the iHateFiles WEBM to WAV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Lifts the soundtrack out of the video and saves it as WAV. The picture is discarded; nothing is re-recorded.
Should you convert WEBM to WAV?
Worth doing when you want the soundtrack of a WEBM on its own: a podcast, an interview, a piece of music from a video. Choose a higher bitrate than you think you need, because the WAV is encoded from the video's audio rather than from a master.
Taking the sound out of WEBM
A WEBM file holds VP8, VP9 or AV1 video with Vorbis or Opus sound. This keeps the sound, discards the picture, and writes the result as WAV (uncompressed PCM). The WEBM original is not altered.
WAV keeps the soundtrack exactly
WAV is lossless, so the sound is written out without a second round of compression. Expect about 10 MB per minute. That is the right choice if you are going to edit the audio, and the wrong one for a podcast you only want to listen to.
WEBM and WAV side by side
| WEBM | WAV | |
|---|---|---|
| Inside the file | VP8, VP9 or AV1 video with Vorbis or Opus sound | uncompressed PCM |
| Compression | Lossy | Lossless |
| Carries sound | Yes | Yes |
| Plays on | every modern browser and Android, but not QuickTime or older iPhones | every editor, DAW and operating system |
| Here | Read and write | Read and write |
What usually goes wrong
About the WEBM. A browser screen recording is usually a WEBM with a broken duration, so players show it as zero seconds or refuse to seek. Converting it to MP4 rewrites the header and fixes the seeking.
About the WAV. Converting an MP3 to WAV makes the file ten times larger without recovering anything. The detail the MP3 discarded is gone.
How to convert WEBM to WAV
- Add your WEBM file. It is read from your disk and stays there.
- Check the settings. The output format is already set to WAV.
- Press convert and the WAV file is saved back to your device.

Questions
How do I convert WEBM to WAV?
Open this page, add your WEBM file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WEBM to WAV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Does extracting audio reduce the quality?
The soundtrack is re-encoded to WAV, so there is one generation of loss at the bitrate you choose. Pick a higher bitrate, or a lossless target like WAV or FLAC, to avoid it.
Can I convert several WEBM files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
