Why convert MP4 to MP3
An MP4 file holds video and sound together. When you only need the sound, such as a talk, a lesson, a song or an interview, keeping the whole video wastes space and is awkward to play in the car or while walking. An MP3 is a small audio file that plays on every phone, computer, car radio and speaker.
The video is read and converted on your own device, so a large file does not have to travel to a server and back. 192 kbps is a good balance for music and speech; pick 320 kbps for the best quality or 128 kbps when the file size matters more.
Frequently asked questions
How do I convert MP4 to MP3 for free?
Select your MP4 video on this page, choose the quality and click Convert to MP3. The audio track is extracted and saved as an MP3 in a few seconds. There is no sign-up, no watermark and no limit on how many times you use it.
Which MP3 quality should I choose?
Choose 192 kbps for most music and speech. 320 kbps is the highest MP3 quality and suits music you will listen to with good headphones. 128 kbps makes files about a third smaller and is fine for podcasts, lessons and voice recordings.
Does converting MP4 to MP3 lose quality?
The sound in an MP4 is usually already compressed in AAC format, so it has to be encoded again as MP3. At 192 or 320 kbps the difference is not audible for most people. The video picture is discarded, which is why the MP3 is much smaller.
Can I convert a YouTube link to MP3?
No. This tool converts video files that are already on your device, such as recordings from your phone, screen captures or downloaded lessons. It does not download videos from YouTube or other websites.
Are my videos uploaded to a server?
No. The audio is extracted inside your browser on your own device, so your videos are never sent to us or stored anywhere. That is also why it is fast: there is no upload or download of the big video file.
