Extract audio from a video
Drop an MP4, MOV or WEBM. If the browser can read the audio track, you can save it as an MP3. Some videos will not decode. That limit is the browser, not an upload error.
Drop a video
Decoded in the browser, then saved as MP3. You can drop several files.
MP3, WAV, M4A, OGG, OPUS, AAC, FLAC
A higher bitrate keeps more detail and makes a larger file.

How do I extract audio from a video?
To extract audio from a video, open the video file in this tool and save its audio track as an MP3. It is meant for MP4, MOV and WEBM files, and the browser must be able to decode the audio track. Your browser decodes the sound on your own device, and an in-browser encoder writes the MP3 at 128, 192, 256 or 320 kbps, with 192 kbps as the default. The video is never uploaded, so a private recording stays private, and no copy is kept. Some videos will not open. That limit comes from the browser's codec support and not from an upload error, and trying another browser or a different export of the video often works. The tool saves only audio. It does not edit or convert the video itself. Use a video you own or have the right to use. It is free, with no account and no watermark.
How to use it
- Open the file Your own MP4, MOV or WEBM.
- Pick a bitrate 192 kbps is the default. Higher keeps more detail and makes a larger MP3.
- Download Download the MP3. Nothing is uploaded.
What the converter does
The browser decodes the file to audio samples, then saves an MP3. It does not create M4A, OGG, FLAC or M4R. If a video or unusual file will not open, the browser could not read its audio.
FAQ
Is the file uploaded?
No. The video is decoded in your browser and only its audio is saved, so the file never leaves your device and no copy is kept. This matters for private recordings. Closing or reloading the tab discards the video. You must own the rights to the video you use. Nothing is sent to a server at any step.
Why is MP3 not identical to WAV?
MP3 throws away some detail to make a smaller file, while WAV keeps the decoded samples at 16-bit, so the two are not identical. The audio in a video is usually already compressed, so extracting it to MP3 compresses it again. A higher bitrate, up to 320 kbps, keeps more detail. The default is 192 kbps. A higher bitrate keeps more of what the browser decoded.
What if decode fails?
Open the page in another browser, or use a different export of the video. Video support depends on the codecs in your browser, and some videos will not decode. That limit is the browser and not an upload error. If the browser cannot read the audio track, the tool cannot extract it.
