A lecture, an interview, a voice message sent as a video — sometimes you only want the sound. This page extracts the audio track from any video your browser can play and saves it as MP3, on your device.
Trim to the part you need, choose the quality, and switch to mono for speech to halve the file. Long recordings can be split into equal parts for sharing.
The video never leaves your device, and the page works offline once loaded.

Pick the video file — from a chat download, a recorder app or a video.
MP3 is already selected; move the quality slider if you need a smaller file.

Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
Which video formats work?
MP4, MOV, WebM, and most MKV and AVI files. If your browser cannot play the video, convert it to MP4 first with the video converter.
Is the quality the same as the video’s audio?
Very close. The track is decoded and re-encoded at the bitrate you choose; 128 kbps or more is transparent for speech.
