How do I convert MP4 to WAV using LetsConvert?

Upload your MP4 file, select WAV as the output format, and click Convert. The tool demuxes the audio from the MP4 container and encodes it as an uncompressed WAV file (PCM 16/24-bit). Once done, download the resulting WAV directly. It works entirely in your browser, no installation required.

Why convert MP4 to WAV instead of keeping the MP4 audio?

MP4 typically stores audio as lossy AAC/MP3, which removes data to save space. WAV stores uncompressed PCM, preserving every detail of the original audio stream (after decoding). This is critical for professional workflows like audio editing, podcast mastering, or DJ sampling, where quality and timing accuracy matter. WAV also has universal compatibility across DAWs and hardware players, though it consumes significantly more storage.

How does the conversion affect video tracks and audio metadata?

Since WAV is an audio-only container, the video track is completely removed. The audio is decoded from the MP4's codec (e.g., AAC) and re-encoded into PCM, meaning the WAV faithfully represents the decoded audio without further loss. Metadata such as album, artist, and cover art may be stripped unless the source MP4 contains ID3 tags that are mapped to WAV's LIST/INFO chunks; this depends on the source file's tags.

Is MP4-TO-WAV free to use?

Yes, MP4-TO-WAV on LetsConvert is 100% free with no registration or hidden fees required.
