How to turn a MOV into an MP3

  1. 1

    Drop the video

    A MOV from an iPhone or a camera, or any MP4 or MKV. The file is read on your computer, so its size doesn't matter much.

  2. 2

    Cut and set up

    Play the sound, stop where the part you want begins and press "use player time". Do the same for the end. Pick the quality and turn the volume up if the recording is quiet.

  3. 3

    Save it

    The MP3 goes to your Downloads. A few minutes of sound takes a few seconds. An hour-long recording can take a minute or two.

Which quality to pick

About how much space a minute of sound takes.

128

128 kbps

About 1 MB a minute. Speech: lectures, interviews, voice notes, a podcast you'll listen to once.

192

192 kbps

About 1.4 MB a minute. Music and mixed sound. A safe choice when you're not sure.

320

320 kbps

About 2.4 MB a minute. The highest MP3 setting. For a live recording or a song you want to keep.

WAV

WAV

About 10 MB a minute, uncompressed. For editing in Audacity, GarageBand or Premiere, where each re-save as MP3 would lose a little.

Questions

Is my video uploaded anywhere?

No. The sound is taken out by your browser on your computer. The video never reaches our server, and we don't see its name.

Will the MP3 sound worse than the video?

iPhone videos store sound as AAC, which is already compressed, so going to MP3 loses a little. At 192 or 320 kbps you won't hear it. If you plan to edit the sound, take WAV.

The video has no sound in the result. Why?

Some cameras record sound in formats a browser can't read, like AC-3 in MKV files or ALAC. In that case the page tells you before converting. Chrome or Edge on a computer read the most formats.

Can I get just one song out of a long video?

Yes, that's what the Cut fields are for. Type the times like 1:20 or 1:02:30, or play the sound and press "use player time" at the right moment.

Can I convert several videos at once?

Not on this page, it takes one video at a time. Each one takes seconds, so a handful is quick to do one by one.
