WAV to MP4 Converter FAQs

Common questions about converting WAV audio files into MP4 videos online.

WAV is audio-only, while MP4 is usually a video format. A background creates the visual part of the MP4 video.

This version is made specifically for WAV input only. For other audio formats, create separate MP3 to MP4 or audio to MP4 tools.
