Getting the sound out of WebM
WebM is the open, royalty-free container built for the web. It is what most browser-based screen recorders produce, and VP9 packs the same picture into noticeably less data than H.264.
The picture is dropped and the sound is written as a variable-bitrate MP3, which every phone, car stereo and podcast host plays. It keeps the sample rate of the audio in your WebM, mono or stereo as it was recorded. If the WebM carries several audio tracks, the MP3 carries one of them. Your WebM itself is not changed.

Before you extract audio from a WebM
The MP3 is a second encode. The audio inside a WebM is almost always compressed already, so extracting to MP3 compresses it again. That is fine for listening, and it is the reason to pick WAV when the audio is going into an editor.
Surround sound comes out as stereo. An MP3 holds at most two channels, so 5.1 audio from a camera, a TV recording or a disc rip is mixed down, while a mono or stereo track is kept as it is.
The whole track comes out, from the first second to the last. To keep only part of it, extract first and then trim the MP3 with the Cut Audio tool.
Extract Audio from WebM: questions
How do I extract audio from a WebM?
Press Extract Audio at the top of this page, upload the WebM and press Extract Audio in the panel. MP3 is already selected, and the audio is ready to preview when the render finishes. A free account downloads it.
What quality is the MP3?
A variable-bitrate MP3 at a high quality setting, with the same sample rate as the audio in your WebM. A mono track stays mono and a stereo one stays stereo; surround sound is mixed down to stereo.
Can I get WAV instead of MP3?
Yes. Switch the output to WAV in the panel before exporting. WAV is uncompressed, so it is several times larger, and it is what an audio editor would rather have.
Does my WebM lose anything?
No. REQO reads the audio out of your WebM and writes a new file; the WebM you uploaded stays exactly as it was.
Is extracting audio from WebM free?
Yes. Extract and preview free, and a free account downloads the result. Free exports and share pages include a small REQO badge. Go Pro to remove it.
