Video to Mp3 Converter is an easy-to-use tool that lets you convert your videos to MP3. The app offers various options for you to choose from, including the bitrate and the type of audio you want to make. You can also choose to mute the video and make a ringtone from it.

It works as simple as a tap-and-play, so you don’t need to do anything else but just install the app and start converting. You can also choose to convert multiple videos at the same time.

Once you’re done converting, you can save the MP3 files to your phone. You can choose to save them in a folder named MP3, so you can easily find them.
