Video to Audio Converter (Extract MP3)

Extract the soundtrack from any video — MP4, MOV, WebM, MKV, AVI, and more — as MP3, WAV, M4A (AAC), OGG, or FLAC. Common conversions include MP4 to MP3, MOV to MP3, WebM to MP3, MKV to MP3, and MP4 to WAV. FFmpeg compiled to WebAssembly does the conversion on your device, so the video never leaves your browser.

How to use Video to Audio Converter (Extract MP3)

  1. Drop in a video file (MP4, MOV, WebM, MKV, AVI, MPEG…).
  2. Pick the audio format — MP3 for compatibility, WAV/FLAC for lossless, M4A for Apple devices, OGG for open-source — and a bitrate where it applies.
  3. Click Extract, listen to the preview, and download the audio file.

Frequently asked questions

How do I convert MP4 to MP3?
Drop in your MP4, choose MP3 as the output format and a bitrate, then click Extract. The audio is pulled out and converted on your device.
How do I extract audio from a video?
Add the video (MP4, MOV, WebM, MKV, AVI, and more), pick an audio format such as MP3 or WAV, and download the extracted track — no upload needed.
Is my video uploaded to a server?
No — FFmpeg runs as WebAssembly inside your browser, so the conversion happens entirely on your device.
Which video formats can I convert to audio?
Anything FFmpeg can demux: MP4, MOV, WebM, MKV, AVI, FLV, WMV, 3GP, MPEG-TS, and more.
Which bitrate should I choose for MP3?
192 kbps is a good balance for most content; choose 320 kbps for music you care about, or 128 kbps for voice recordings and the smallest files.
What if my video has no sound?
The tool detects videos without an audio track and tells you — nothing is converted.
