Extract Audio from Video saves just the sound of a video as an audio file, ready for an editor, a transcription tool or a podcast. Choose M4A (AAC) to stay close to the original, or MP3 for the widest compatibility. Interviews, meetings and voice notes often hold private conversations; the extraction runs in your browser, so they are not uploaded anywhere.
When you need just the audio
| Situation | Why audio only |
|---|---|
| Transcribing an interview | Transcription tools accept audio files |
| Editing a podcast | Audio editors work faster without video |
| Sending a voice recording | A few MB instead of hundreds |
| Keeping the music of a clip | Plays in any music app |
M4A or MP3
| M4A (AAC) | MP3 | |
|---|---|---|
| Sound at the same bitrate | Slightly better | Good |
| Plays on | Phones, Mac, Windows, most apps | Everything, including car stereos and old players |
| Best for | Editing, archiving, transcription | Sharing with anyone, older devices |
This page starts on M4A because most phone and camera videos already store sound as AAC. If you are not sure what the other person uses, MP3 is the safe choice.
Which quality to pick
- 128 kbit/s for speech: interviews, lectures, meetings, voice memos. About 1 MB per minute.
- 192 kbit/s for music and mixed content. About 1.4 MB per minute.
- 320 kbit/s when you want the highest setting, for example a concert you filmed. About 2.4 MB per minute.
The audio cannot sound better than what the video recorded. A phone microphone at 320 kbit/s is still a phone microphone; the higher setting only avoids adding any loss of its own.
What to do with the audio next
The file is ready for other tools on this site, all of which also run in your browser:
- Audio to Text turns speech into a transcript.
- Noise Reduction cleans up hum, wind and room noise.
- Audio Cutter keeps one part, such as a single answer or a song.
- Vocal Remover separates the voice from the music.
Tips
- For a long recording, extracting audio first and then transcribing or cleaning it is faster than working on the full video.
- Long videos work too; keep the tab open until the progress bar finishes.
- The audio has the same length as the video, so timestamps in a transcript match the original.
