About the Video to MP3
Extracting the audio from a video is useful for saving a song from a concert clip, turning a lecture or interview into a podcast file, or sending a voice recording without the large video attached.
SoundBench reads the audio track straight from the video file on your device. Phone videos are often hundreds of megabytes, and nothing has to be uploaded, so it is both private and fast.

- Drop a video file (MP4, MOV, MKV, WEBM, AVI and more) onto the page.

- Click Export to download the audio file.
Frequently asked questions
How do I convert an MP4 video to MP3?
Drop the MP4 onto this page, keep MP3 selected and click Export. The audio track is decoded and encoded as MP3 in your browser.
Can I extract audio from an iPhone video?
Yes. iPhone videos are MOV or MP4 files with AAC audio and open directly. On the iPhone itself, pick the video from Photos in the file picker.
Is there a file size limit?
No fixed limit. Because the file is processed on your device, the practical limit is your device's memory. Very long videos work best on a computer.
Can I keep the original audio quality?
Choose WAV or FLAC for a lossless copy of the decoded soundtrack, or AAC at 256 kbps for a small file close to the original.
