Extract the soundtrack from any video — MP4, MOV, WebM, MKV, AVI, and more — as MP3, WAV, M4A (AAC), OGG, or FLAC. 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)
Drop in a video file (MP4, MOV, WebM, MKV, AVI, MPEG…).
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.
Click Extract, listen to the preview, and download the audio file.
Frequently asked questions
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.
