Upload a video to extract its audio
This free tool strips the audio track out of any video and saves it as MP3, WAV, or M4A — perfect for turning a lecture recording, podcast video, or music clip into a standalone audio file. Everything runs locally in your browser using FFmpeg compiled to WebAssembly, so your video is never uploaded to a server.
Is this video to MP3 converter really free?
Yes. There's no signup, no watermark, and no limit on how many videos you convert — extraction runs entirely in your browser.
Does my video get uploaded to a server?
No. The entire conversion happens locally using FFmpeg compiled to WebAssembly. Your file never leaves your device.
What video formats can I upload?
MP4, WebM, and MOV (QuickTime) are supported, up to 500MB per file.
What bitrate should I choose?
For spoken word or podcasts, 128 kbps keeps files small without noticeable quality loss. For music, 192-256 kbps is a solid balance of size and fidelity, and 320 kbps gets you as close to the original quality as MP3 allows. If file size doesn't matter, choose WAV for a lossless, uncompressed copy of the audio.
Can I extract just part of a video's audio?
Yes. Turn on "Extract only part of the video" and set a start and end time — only that range will be exported.
Why does my file have no sound?
Some videos — especially screen recordings or muted clips — simply don't have an audio track to begin with. We check for this before handing you a file: if no audio stream is detected, you'll see a clear error instead of a silent file that looks like it worked but isn't actually usable.
