Pull the audio out of an MP4 file and save it as an MP3 — no software to install, and your video never leaves your device.
How to Convert MP4 to MP3
Upload your MP4 file, choose an audio quality — 128, 192, or 320 kbps — and click "Extract Audio." The soundtrack is pulled out and downloads automatically as an MP3.
Choosing an Audio Quality
128 kbps keeps the file small and works well for spoken word. 192 kbps is a solid middle ground that suits most music and casual listening. 320 kbps gives the highest quality an MP3 can offer, worth the larger file size when the audio detail matters.
Good Uses for This Tool
Saving the audio from an MP4 lecture or interview recording, pulling a song out of a downloaded MP4 music video, converting a phone-recorded MP4 video into an audio file, or getting just the soundtrack from an MP4 for use somewhere audio-only.
Is It Actually Private?
Yes. The extraction happens entirely in your browser using WebAssembly — your file is never uploaded to a server.
