MP4, MOV, WebM, MKV and more — the file stays on your device
This is a free video to MP3 converter that works on the video files already sitting on your own device. Open a recorded lecture, a meeting recording, an interview, a rehearsal you filmed or any other clip, and the tool separates the sound from the picture and hands you a plain audio file. Everything happens inside the browser: the video is read straight from your disk, decoded locally, and the audio is encoded on your own machine using a WebAssembly build of the LAME encoder. Nothing is uploaded — which matters enormously for meeting recordings, interviews and other material you simply cannot hand to someone else's server. Choose MP3 for a small file that plays on any phone, laptop or car stereo, or WAV when you need untouched PCM for further editing. The Voice preset encodes speech at exactly half the size of the Standard setting, so a two-hour lecture ends up small enough to carry around without a second thought.
Drag a video into the box or click to pick one from your device. MP4, MOV, WebM and MKV all work, and the file is read locally — it is never sent anywhere.
Choose MP3 for everyday listening or WAV for uncompressed audio. With MP3, take Standard for music or Voice for talks and meetings at half the file size.
Click “Extract audio” and follow the progress bar. When it finishes, play the result right on the page to check it, then download the MP3 or WAV.
Decoding and encoding both run in your browser. Confidential meeting recordings and interviews stay on your own machine, and the tool keeps working even if you go offline mid-way.
MP3 for a compact file that plays anywhere, WAV for untouched 16-bit PCM when the audio is going into an editor afterwards.
The Voice preset encodes at 96 kbps in mono, halving the size of a lecture or meeting recording while every word stays perfectly clear.
MP4, MOV, WebM, MKV, M4V and more are parsed directly by the tool, including some files a browser refuses to play back.
No account, no credits, no daily cap and no audio stamp over your recording. Convert as many of your own files as you like.
A genuine progress bar tracks the conversion, the output size is estimated up front, and the finished audio can be played in the page before you download it.
Turn a recorded class into an audio file you can listen to while walking or commuting. The Voice preset keeps a two-hour lecture small enough to carry on a phone.
Pull the audio out of a recorded meeting for note-taking or transcription, without handing a confidential discussion to an online service you do not control.
Journalists and researchers can strip the audio from filmed interviews and archive it, with the source material staying private from beginning to end.
Lift the soundtrack from a rehearsal, a performance you filmed or a clip you shot yourself, and keep it as a standalone audio file.
No. The file is read from your disk, decoded and re-encoded entirely inside your browser, and the result is handed straight back to you. Nothing is transmitted at any point, so even sensitive meeting or interview recordings never leave your own machine — and the tool keeps working on an unreliable connection, or none at all.
Any video file stored on your own device: MP4, MOV, WebM, MKV, M4V and similar containers are all read directly. Because the container is parsed by the tool itself rather than by the browser's media player, some files that will not play back in a browser tab can still have their audio extracted successfully.
MP3 for almost every purpose — it is compressed, plays on any phone, laptop or car stereo, and is far smaller. Choose WAV when the audio is going into an editor and you want uncompressed 16-bit PCM with no generation loss. Expect WAV to be roughly 3.7 times the size of a 192 kbps MP3 for a mono source, and about 7.3 times for a stereo one.
Standard encodes at 192 kbps and stays in stereo when the source is stereo, which suits music and anything where room atmosphere matters. Voice encodes at 96 kbps in mono, producing a file exactly half the size — ideal for lectures, interviews and meetings, where only the speech carries information. MP3 uses a constant bitrate, so the bitrate alone decides the file size; the mono setting does not shrink it further, it simply spends every bit on the one channel that matters instead of two identical ones.
Because the video genuinely contains only a picture. Screen recordings made with the microphone disabled, silent camera clips and some exported animations carry no audio stream at all, so there is nothing to pull out. Open the file in a media player to confirm before trying again.
Long recordings are fine — a lecture of several hours is well within reach as an MP3. The real limit is memory rather than time: the finished audio has to be assembled as a single block inside the browser tab, so the tool estimates the output size before it starts and warns you when a setting would be too large. WAV hits that ceiling far sooner than MP3, because PCM is uncompressed. The size of the video itself does not matter, only the length of its audio: a huge 4K file with two minutes of sound converts as easily as a small one.
MP3 is a lossy format, so re-encoding does cost a little. At 192 kbps the difference is inaudible in ordinary listening, and at 96 kbps mono speech stays completely clear. If you want no loss at all, choose WAV, which writes the decoded samples out as uncompressed PCM. The first time you export an MP3, the encoder itself (about 311 KB) is fetched once — every export after that starts instantly.
