The mp4 format is one of the most common formats on the net, because the video container is particularly efficient when it comes to saving and is also used for streaming over the net – you can access mp4 files (unnoticed) even if you are watching videos on platforms such as Watch Vimeo or YouTube. Now it is important to know when you need to convert mp4 to mp3 in order to play it better and why you should convert mp4 to mp3 in many cases in order to pull only certain parts out of the mp4 container. In principle, unlike other file extensions, the mp4 format is not particularly meaningful when it comes to the content. Because an mp4 can contain not only video content, but also audio formats. It becomes particularly strange when an mp4 does not even have the file extension mp4, because there are different file extensions that indicate the content. However, these endings are not mandatory, but have been proposed by Apple to clarify content and to use certain additional functions. An example of this is about an m4b file. This format from mp4 stands for an audio book (audio book) in which bookmarks can also be set. This is where it can be worthwhile if you convert the mp4 to mp3, because many of the sub-formats of mp4 can no longer be played on older devices. Or are unsuitable, for example, to serve as a ringtone. Converting Mp4 to mp3 can also be useful if you want to extract a sound file from a video file – for example, you can load a music video and use the audio track as a ringtone. This extraction can also be useful when sending mp4 files between editing programs in order to separate the audio track. In addition, mp3 is a very simple method to compress audio files. Although this involves losses in terms of sound quality, these losses can usually be overcome when sent via email and saved on devices with limited storage capacity.

No, because the MP4 file usually contains the audio track as aac. However, as aac itself is already a lossy format in which, for example, inaudible frequencies have been removed, this is not perceptible in most cases. To enable lossless conversion, .flac or .wav should be selected as the target format. In this case, the information from the audio track of the MP4 container is transferred exactly. However, .flac and especially .wav files are significantly larger.
After uploading, the conversion often takes between a few seconds and minutes, depending on the length of the audio track.

As the video part accounts for the largest proportion of the file size (90 % and more), the resulting MP3 file is considerably smaller. This is not a sign of a loss of quality in the audio part, but simply the result of the conversion. The MP3 file is therefore usually 90-95% smaller than the MP4 file with video.
