- Pick the output format and bitrate.
- Optionally convert to mono or change the sample rate.
- Click Convert, wait for the progress bar, then Download.
Which audio format should I choose?
- MP3: plays everywhere. Best for sharing and old devices.
- M4A (AAC): better quality than MP3 at the same size; native on Apple devices.
- Opus / OGG: most efficient for voice and the web; not supported by every player.
- WAV / FLAC: lossless. WAV for editing software, FLAC for a smaller lossless archive.
Frequently asked questions
Which audio formats are supported?
Input: MP3, WAV, OGG, Opus, M4A, AAC, FLAC, WMA and more, plus the soundtrack of MP4, MOV, WebM, MKV and AVI videos. Output: MP3, WAV, OGG (Vorbis), Opus, M4A (AAC) and FLAC.
How do I extract audio from a video?
Drop the video file (for example an MP4 or MOV) and choose MP3, WAV or M4A. The video track is dropped and only the sound is saved.
Which bitrate should I pick?
192 kbps MP3 or 128 kbps M4A or Opus sound transparent to most listeners. Use 320 kbps for archiving, or FLAC or WAV for lossless copies.
Does converting MP3 to FLAC improve quality?
No. A lossless format keeps what is already there, it cannot restore detail removed by MP3 compression. It only makes the file bigger.
Are my files uploaded?
No. Everything runs locally in your browser with ffmpeg in WebAssembly. Very large files may be slow or run out of memory, particularly on phones.
