Extract Audio From Video
Keep the sound, drop the picture.
A recorded talk, an interview, a lecture or a piece of music captured on video is often only useful as audio. Audio is a fraction of the size, plays in the background, and goes into a podcast app or a transcription tool that has no interest in the picture.
Choose MP3 for universal compatibility, AAC or Opus for better quality at the same bitrate, or WAV when you need uncompressed audio for editing. The video stream is discarded entirely, so this is much quicker than a full conversion — and it happens on your own device.
How to use it
- 01Drop in the video.
- 02Choose a format — MP3 plays everywhere, AAC and Opus are more efficient, WAV is uncompressed.
- 03Pick a bitrate: 192 kbps is transparent for most listening.
- 04Extract and download the audio file.
Frequently asked questions
Which format and bitrate should I pick?
MP3 at 192 kbps is a safe default that plays anywhere and sounds fine. For speech alone, 96-128 kbps is plenty and halves the size. Use WAV only if the audio is going into an editor, since it is roughly ten times larger.
Does extracting reduce the audio quality?
Slightly, since the audio is re-encoded from whatever the video contained. At 192 kbps and above the difference is inaudible for normal listening. WAV avoids further lossy compression, though it can't restore what the original video already discarded.
What if the video has no audio?
The tool checks for an audio track before starting and tells you if there isn't one, rather than producing an empty file.
Why does MP3 take a moment longer to start?
MP3 encoding is the one format browsers don't provide natively, so the tool loads a small MP3 encoder the first time you choose it. Every other format uses your device's built-in codecs directly.
