MP4 to MP3 FAQ

How do I convert MP4 to MP3?

Drop your MP4 file onto the upload area (or click Choose file), pick the output quality if you like, then click Extract. Download the MP3 when it's ready.

Does MP4 to MP3 keep the video?

No. This tool extracts only the audio track and discards the video, so you're left with a compact MP3 of just the sound.

Will the audio quality be as good as the original?

The MP3 is encoded from the video's existing audio track. At a high bitrate it's very close to the source; MP3 is lossy, so pick a higher bitrate to keep quality maximal.

How long can the video be?

Because processing happens on your own device, longer videos take more time and memory, but there's no server-imposed size cap. Very large files depend on your device's available RAM.

Is my video uploaded to a server?

No. The audio is extracted entirely inside your browser and your video never leaves your device. Nothing is stored or logged.
