Audio extractor for any video file
Pull the sound out of a video and keep it as MP3, WAV or M4A. The file is read from your own disk, so nothing is uploaded and nothing is stored.
Files are processed on your device · nothing is uploaded, stored or logged
How it works
Pick your file. The browser reads it straight from disk. There is no upload progress bar, because there is no upload.
The encoder loads once. A WebAssembly build of FFmpeg, around 30 MB, downloads the first time you use the site and stays cached afterwards.
Your processor does the work. Everything happens in this tab, at roughly half of real time on a modern laptop.
Save the result. The finished file is assembled in memory and handed to your downloads folder.
Three formats, three different jobs
MP3 is the one to pick if the file is going to be listened to — in a car, on a phone, in a podcast app. It is compressed, small, and understood by literally everything.
WAV is uncompressed. The file will be large, roughly 10 MB per minute, but nothing is thrown away. Choose it when the audio is heading into Audacity, a DAW or a transcription tool that works better with raw input.
M4A copies the audio out of the video without re-encoding it at all. It is the fastest option and loses nothing, because most videos already store their sound as AAC — which is exactly what an M4A holds.
The one worth knowing about
If you only care about keeping quality, M4A wins outright. It skips the decode-and-recompress step entirely, so the audio in the output is bit-for-bit the audio from the video. The only reason not to use it is that older devices sometimes prefer MP3.
If you want the opposite — keep the picture and drop the sound — use remove audio.
Common questions
Which format should I use for a podcast?
MP3. Every hosting platform accepts it and listeners' apps expect it.
Can I get better quality than the original?
No. The audio inside the video sets the ceiling. WAV preserves what is there but cannot add detail that was never recorded.
What if my video has no sound?
The conversion will fail with an error rather than producing a silent file. That usually means the recording captured no audio device.
Do my files get uploaded?
No. Everything runs in this tab, on your machine.
