Convert video to mp3 on Android manually


In this method, we will convert the video to mp3 audio manually by renaming the file. Please note that this is not the right way to convert the files. As you are just changing the format, so the media player apps that support MP3 will be able to play the audio part only.

Another important thing is that the size of the file will not be changed. You need a file manager app for renaming the file. Either you can use your phone's built-in file manager or you can download any third-party app from Play Store such as File Commander. Follow these steps after that -
  1. Open the file manager app on your Android phone.
  2. Go to the folder/location where the video is saved.
  3. Select the video file by long-pressing on it and then click the Rename option.
  4. Now you have to remove the file extension of the video and add mp3 in its place at the end of the file name (after the dot symbol).
