MP4 to MP3

Convert MP4 to MP3 in three steps

1. Choose one or more MP4 files, or try the included sample.
2. Pick your MP3 bitrate and press Convert to MP3. Keep this tab open while it works.
3. Listen to the preview and save individual files or download the batch as a ZIP.

Extract the soundtrack from an MP4 video

MP4 is the most common video container. Turning it into an MP3 is useful for lectures you want to listen to, music videos, recorded webinars, and screen recordings where only the narration matters. The audio is extracted from the primary track, so the video itself is never decoded and the file is not uploaded. Files with the .m4v extension use the same container and work here too.

Longer videos and bitrates

The conversion reads the file from disk in pieces, but encoding still takes processor time, roughly proportional to the length of the video. A one-hour lecture at 128 kbps becomes an MP3 of about 58 MB. Choose 192 kbps for music videos. If your MP4 has several audio tracks, the primary track is converted. Videos with protected streaming DRM cannot be opened by any browser tool.

Troubleshooting and tips

If you only want a short quote or song section, trim the video first, since conversion processes the whole file. Videos from screen recorders sometimes have audio on a second track. The converter uses the primary track, which is almost always the one you want. Streaming downloads protected by DRM, such as purchased movies, cannot be opened. For an edited soundtrack with silence removed, use the silence remover instead.
