Video to MP3: extract audio from any video
Save the soundtrack, a lecture or a voice note from a video as MP3, M4A, WAV, FLAC, OGG or Opus. The video track is dropped; the audio never leaves your device.
Copy or convert?
Inside a video, the audio is its own stream, usually AAC in MP4/MOV, Opus or Vorbis in WebM, and anything at all in MKV. If the format you pick can hold that stream as-is, the converter copies it: done in a second, bit-identical to the original. Otherwise it decodes and re-encodes.
| Source audio | Pick for a lossless copy | Pick for compatibility |
|---|---|---|
| AAC (MP4, MOV, most phones) | M4A | MP3 |
| Opus (WebM, screen recorders) | Opus | MP3 |
| Vorbis (older WebM, OGV) | OGG | MP3 |
| MP3 (many AVI files) | MP3 | MP3 |
| PCM (camcorders, ProRes MOV) | WAV / FLAC | MP3 |

Questions
Is extracting audio lossless?
It can be. Choose M4A for an AAC source (most MP4 and MOV files), or Opus for WebM with Opus, and the audio stream is copied byte for byte. MP3, WAV and FLAC decode the audio first; WAV and FLAC then store it without further loss.
Which format should I pick?
MP3 for maximum compatibility, M4A to keep the original AAC untouched, WAV for editing, FLAC for lossless archiving at half the size of WAV.
Can I extract just part of the audio?
Yes. Set the start and end times in seconds before you press Extract.
Does it work with long videos?
Yes. Only the audio is processed, so even a two-hour video is quick, and memory use stays small because audio is a fraction of the file.
