Good to know: the audio is extracted on your device, so nothing is uploaded. Pulling out audio is much lighter than converting video, but very large or long files still use memory. Maximum file size is 1 GB, one file at a time. The compatible engine downloads about 31 MB the first time you use it.

Extract Audio from Video is a free tool that pulls the audio track out of a video entirely in your browser, with nothing uploaded. Save the result as MP3, M4A (AAC), WAV or OGG (Opus), choose the bitrate and mono or stereo, or pick Same as source to copy the existing audio with no re-encoding and no quality loss. You can optionally trim to a section. It uses fast hardware-friendly encoding through the WebCodecs API where possible and falls back to a built-in engine that downloads about 31 MB the first time. The maximum file size is 1 GB.

Frequently asked questions

Are my videos uploaded anywhere?

No. The audio is pulled out of your video inside your browser on your device, and nothing is ever sent to a server.

Which format should I pick?

MP3 plays almost everywhere and is the safe default. M4A (AAC) is a bit smaller at the same quality. WAV is uncompressed, so it is lossless but the files are large. OGG (Opus) is very efficient at small sizes. Same as source copies the audio already inside the video with no quality loss.

What does "Same as source" do?

It copies the existing audio track straight out of the video without re-encoding it, so it is instant and loses no quality. The saved format depends on what is inside the video, which is most often M4A (AAC) for MP4 files.

Does the bitrate matter?

For MP3, M4A and OGG a higher bitrate means better quality and a bigger file; 192 kbps is a good balance for music, and 128 kbps is fine for speech. WAV and Same as source ignore the bitrate because they do not re-compress.

Is there a size limit?

Yes, 1 GB per video and one at a time. Pulling out audio is much lighter than converting video, but very large or long files still use memory, and the compatible engine downloads about 31 MB the first time.

What are the two engines?

Fast mode uses your device and needs no download; MP3 and WAV work in every modern browser, and M4A and OGG use your browser's built-in encoder. Compatible mode uses a built-in engine that works more widely but downloads about 31 MB and is slower. It picks automatically and you can override it.
