MP4 to MP3 converter
Open an MP4 and save its sound as an MP3. It runs in your browser, so the video never leaves your device.
How it works
Tap the box above and choose your video.
320 kbps for music, 128 kbps for speech.
Press Convert, then Download.
Why convert MP4 to MP3?
An MP4 holds both video and sound. If you only want to listen, an MP3 is much smaller and plays on every phone, car stereo and music app.
Only need part of it?
Drag on the waveform to keep just the section you want, for example one song from a concert video.
