The Waveform Audio File Format (WAV) was originally developed by Microsoft and IBM as a standard for storing audio on personal computers. WAV files are typically uncompressed; this results in high-quality audio but also large file sizes compared to compressed formats like MP3.
MP4 is a multimedia format that stores video, audio, subtitles, or other data. MP4 files are widely used for sharing videos on the internet and are compatible with a broad range of devices and platforms.
So, why would you convert WAV to MP4? Primarily because you want to use the audio of a WAV file in a video format. Or, you're looking to apply specific types of effects like using a waveform generator to create a sound wave visual based on music, speech, or some other type of audio.
In short: MP4 files are a popular compressed video format that's used to publish online, while WAV is a high-quality audio format that doesn't support video and typically demands larger file sizes. Fortunately, with Kapwing's audio and video converter tools you can convert WAV to MP4 along with a wide variety of other file types.

Why convert your WAV files to MP4?
MP4, which stands for MPEG-4 Part 14, is a popular format for digital media that can store video, audio, images, and subtitles. There are a number of reasons why you should consider using MP4s as the default file type for your videos:
1. File size: MP4 files use advanced video codecs that offer better video compression compared to other formats. The result is smaller file sizes without a meaningful drop in quality—great for online videos.
2. Compatibility: MP4 is widely supported and works across almost all devices and video or social media platforms.
3. Flexibility: MP4s can contain video, audio, images, and subtitles. This makes MP4s a convenient format for delivering full multimedia experiences in a single file.

Is a WAV a video file?
No, the WAV format is used for uncompressed audio files. WAV files can be added to videos as an audio later, but to play a WAV as a video, you'll need to convert the .wav file to an MP4.
Can a WAV be used in an MP4?
WAV files can be added as an audio layer when editing a video in tools like Kapwing. You can then edit the video footage and WAV audio together as an MP4 file. However, since MP4s are "lossy" files and WAVs are uncompressed files, the quality of the .wav audio will be slightly reduced in the final video.
