Video sites can be used not only to present moving pictures, but many authors also upload great audio work to get more attention. However, we need to note that some video platforms do not support directly uploading songs in regular formats, such as WAV files, but only in digital video formats. If users want to upload WAV audio to the platform, they need to convert WAV to MP4 first and match the song with a moving image or an album artwork as the cover. This article was created to deal with this scenario. We will provide the three best WAV to MP4 converters, no matter whether the readers use a PC or Mac or prefer to accomplish the task online.

Part 1: Why Should We Convert WAV to MP4

Let's start with a brief introduction to the two formats, WAV and MP4. Most people are more than familiar with MP4, a digital format that can store video and audio and can also accommodate images and subtitles. MP4 is the format we use most often when uploading, editing, and sharing videos on the Internet, while WAV is an audio format that is not only the default format for Windows operating systems but also the format we use most often when storing songs on CDs.

At this moment, some people may wonder, MP4 is a video format, but WAV is an audio format; when will the two be related, and when do they need to be converted to each other? The answer is when we need to upload audio, album, or podcast content to a video platform. The MP4 format is obviously much more compatible than WAV. When encountering some platforms that don't support WAV format or don't support directly uploading pure audio files, in order to avoid these obstacles, we need to convert WAV to MP4. Also, sometimes, to showcase the audio, we have to give it an image or a cover. At this point, we can create an MP4 video containing the album art and WAV audio files and then upload it.

Yes. There may be some loss of quality, but it is not evident in the specific document, and the difference is mainly inaudible to the human ear.

Which is better, WAV or MP4?

The WAV format provides higher-quality audio and is most compatible with Windows systems. However, WAV files are larger and may be less convenient to distribute. MP4 files make some sacrifices in sound quality to achieve a smaller size.

Does YouTube support WAV?
