Why MP3

MP3 is still the format that works everywhere: old car stereos, Bluetooth speakers, smart TVs, voice message apps and music players all read it. Saving a talk, a lesson, a song from your own video or the sound of a family clip as MP3 means you never have to worry whether it will play.

The converter decodes the audio of the MP4 and encodes it as MP3 at 192 kbit/s, which sounds the same as the original for nearly all listeners. A minute of stereo audio comes to about 1.4 MB.

Long videos and many files

Drop a whole folder of videos and each one becomes an MP3. Hour long lectures work too, because the file is processed on your device instead of being uploaded. Download the results one by one or together as a ZIP.
