Good to know
What to expect
- Only the soundtrack is saved; the picture is dropped.
- The audio is saved as MP3 at 192 kbps (you can pick 128 to 320 kbps).
- If the video's audio is already MP3, it's copied without re-encoding, so there's no quality loss. Picking a bitrate re-encodes it at that bitrate instead.
- Copy-protected (DRM) files can't be converted.
- Very long videos can run out of memory, especially on phones.
FAQ
Questions, answered
Is the video to MP3 converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. Everything runs inside your browser with Mediabunny and your browser's WebCodecs video encoders, so your files never leave your device. Once the page has loaded, it even works offline.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in current versions of Chrome, Edge, Safari, and Firefox. Phones handle short clips well, and long or 4K videos convert best on a computer.
Can I convert a YouTube video to MP3?
Only from a video file you have on your device. This converter doesn't download from YouTube or other websites, because that usually breaks their terms of service and copyright. For your own videos, download them from YouTube Studio first.
Does converting MP4 to MP3 lose quality?
MP3 is a lossy format, so the audio is compressed. At the default bitrate most people can't hear a difference. Choose 256 or 320 kbps for music you care about.
How long does it take?
When the video can be copied without re-encoding, a few seconds. Otherwise it depends on the video's length and resolution and on your device. With a hardware encoder, a 10-minute 1080p video usually takes a few minutes on a laptop.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and a computer can usually handle videos up to about 2 GB.
