MP4 to MP3 Converter is an easy-to-use app for Android to convert video files to audio files or extract audio from video files at very fast speed.

MP4 to MP3 Converter can convert video files such as MP4, MOV, WEBM, AVI, MKV, WMV or M2TS to audio files such as MP3, OGG, AAC, WAV or M4A. For example: MP4 to MP3, MP4 to AAC, MOV to MP3 or MKV to MP3. The settings include start position, duration, audio bitrate and sample rate.

MP4 to MP3 Converter can also extract audio tracks from videos. For example: extract M4A from MP4, extract MKA from MKV or extract OGG from WEBM. The output audio is exactly the same as in the video file. The audio extraction works very fast because there's no conversion, decoding or encoding during extraction. It only takes a few seconds to extract audio from a 2 GB video file. This is very helpful for very large videos.

Additionally, we provide a free online MP4 to MP3 conversion service which doesn't occupy your phone CPU.
