Is my video uploaded?

No. The video stays on your device: it is read and converted in your browser.

Up to 1 GB and 30 minutes, free of charge.

What happens to the picture?

It is discarded. Only the sound is decoded and saved, as an MP3.

What if the video has no sound?

The conversion is refused: there is nothing to save as an MP3.

What quality do I get?

"Smaller file" uses 128 kbps, "Balanced" 192 kbps and "Better quality" 320 kbps.

Convert MP4 to MP3

This tool reads the sound of an MP4 video and saves it as an MP3 file, in your browser. The video is never uploaded: the audio track is decoded and re-encoded as MP3 on your device, while the picture is discarded without ever being decoded. A video with no sound is refused, and if your browser cannot decode its audio, GRID16 says so instead of turning it into silence.
