About the MP4 to WAV converter
The MP4 to WAV converter changes a MP4 file into WAV, right in your browser. Upload your MP4 file and download the WAV version — free, with no sign-up, no watermark, and nothing uploaded.
MP4 is the most widely supported video format — it plays on virtually every phone, browser and player. WAV is uncompressed audio — large files at full quality, ideal for editing. The conversion runs on an in-browser build of ffmpeg, so your file is processed entirely on your own device and never sent to a server.
