MP4 to MP3 FAQ
Is this MP4 to MP3 converter free? +
Yes. Convert as many videos as you like for free, with no sign-up, no watermark and no file size limit of ours.
Is my video uploaded? +
No. The audio is taken out of the video right in your browser, so the file never leaves your device.
Which videos work? +
MP4, MOV, M4V, WebM and MKV files, including iPhone and Android recordings, screen recordings and Zoom or Teams downloads. The video needs a sound track.
Which format should I pick? +
MP3 plays everywhere: 128 kbps is plenty for speech, 192 or 320 kbps for music. M4A keeps the video's original audio without re-encoding, so it's the fastest and has no quality loss. WAV is uncompressed, for editing software.
Does it work on a phone? +
Yes, in a recent Chrome, Edge or Safari. Very long videos need a lot of memory, so a computer is faster for those.
Can I get the words instead of the audio? +
Yes. Upload the video or the MP3 to Audio & Video to Text for a free transcript.
Can I convert a YouTube video to MP3? +
No. This works on video files on your device. For the words in a YouTube video, use the free YouTube Transcript tool.
