How to convert MP4 to MP3
- Drop one or more videos into the box.
- Choose MP3 (small, plays everywhere) or WAV (lossless), and the quality.
- Download the audio files when they're done.
Which quality should I choose?
- 128 kbps — speech, podcasts, lectures.
- 192 kbps — music in good quality (default).
- 320 kbps — the best MP3 quality.
- WAV — no compression, for editing in Audacity, GarageBand or a video editor.
Private and fast
Your browser decodes the video's sound and an MP3 encoder runs on your device. Nothing is uploaded, so even large or private recordings stay with you.
Frequently asked questions
Is my video uploaded?
No. The audio is extracted in your browser and never leaves your device.
Can I convert iPhone videos (MOV)?
Yes, as long as your browser can play the file. Most iPhone videos work in Safari, Chrome and Edge.
Can I download audio from YouTube?
No. This tool converts video files you already have on your device.
Is there a size limit?
Up to 500 MB per file. Very long videos need a lot of memory, so close other tabs if a conversion fails.
