Convert MP4 to MP3 online for free: upload the video and keep only the audio, as a 320 kbps MP3. It also works to extract audio from any video recorded on your phone (iPhone MOV, Android MP4) or downloaded from anywhere.
How to convert MP4 to MP3
- Upload the video by dragging it onto the upload area or clicking ‘Choose file’. MP4, MOV, WEBM, MKV, AVI, M4V, 3GP and FLV are accepted.
- Keep MP3 as the output (or pick WAV, M4A, FLAC or OGG) and click ‘Convert’.
- Download the MP3. The picture is dropped, so the file is a fraction of the video’s size.
Why extract audio from a video
- Keep the music from a video or a concert you filmed.
- Listen to a recorded lecture, talk or meeting like a podcast.
- Turn a voice memo recorded as video into audio you can send or transcribe.
- Pull the audio track out to edit it in your sound software.
Limits, stated plainly
- The video can be up to 80 MB. For a bigger one, trim it first or use a lower-resolution copy: the audio is the same.
- If the video has no audio track, there is nothing to extract and the conversion will fail.
- Files are deleted from the server shortly after conversion.
Frequently asked questions
Is converting MP4 to MP3 free?
Yes, no sign-up and no watermark.
Is quality lost?
Audio is encoded as MP3 at 320 kbps, the format’s highest bitrate. If you need uncompressed audio, choose WAV or FLAC.
Does it work with iPhone videos?
Yes: iPhone videos are MOV files and convert the same way. On mobile, tap ‘Choose file’ and pick the video from your gallery.
What if the video is on YouTube or TikTok?
Then there’s no need to download it first: paste the link into the YouTube to MP3 converter or TikTok and Instagram audio to MP3.
