Free MP4 to WAV Converter

No. The page downloads the conversion software, then reads and processes your selected file locally. There is no media upload or server conversion fallback. The site's ordinary cookie and analytics preferences still apply.

A filename extension describes a container, which can hold different codecs. The browser must support decoding the actual source tracks and encoding the selected output. Protected, damaged, and unsupported files receive an error. Try another supported desktop browser if a codec is unavailable.

Re-encoding can lose detail. Compatible video tracks may be copied at original quality; MP3 is re-encoded and WAV is exported as 16-bit PCM. Converting a compressed recording to WAV does not recover missing detail. Output size is limited to 250 MB and may be larger than the input.

Only the primary video and audio tracks are used. Audio outputs discard the video. Re-encoded audio is mono or stereo; compatible audio copied into a video keeps its channel layout. Additional soundtracks, subtitles, chapters, descriptive tags, and attachments are not carried over. The tool stops if it cannot retain a required primary track.

The tool is designed for supported desktop browsers. Some phones may work, but codec support, memory, and background tab restrictions vary. The tool processes one file at a time.
