Convert WebM to WAV.
Pull the soundtrack out of a WebM video, such as a browser or meeting recording, as uncompressed WAV.
From a recording to an edit
Browser screen recorders and meeting tools save WebM. Extract the sound to WAV to clean up a podcast, cut an interview or prepare it for transcription.
Sample rate kept
WebM audio is usually 48 kHz, and the WAV stays at 48 kHz, so it lines up with video projects.
Size change
WAV is uncompressed: about 11 MB a minute for stereo at 48 kHz.

Extracting WAV from WEBM
This pulls the audio track out of your WEBM and encodes it as WAV; the video is discarded. WAV is lossless, so the audio is kept faithfully.

Common questions
Is it free?+
Yes. Convert WebM to WAV free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Why not just open the WebM?+
WebM audio is usually Opus, which many editors, DAWs and transcription tools cannot read. A WAV opens in all of them.
Will it sound better than the video?+
No. The WAV keeps exactly what the soundtrack decodes to, with no further loss, but cannot add detail.
