The video stream is discarded; this is the right tool when you need clean source audio from a video for editing, transcription, or archival. The conversion runs locally via ffmpeg.wasm, so your file never leaves your device. Performance depends on your CPU: extracting audio is typically faster than re-encoding video, but very long or 4K sources may still be slow. For best results keep inputs under about 500 MB.","category":"video","categoryName":"Video","keywords":["mp4 to wav","convert mp4 to wav","mp4 to wav converter","mp4 to wav online","mp4 to wav free","online mp4 to wav","change mp4 to wav","mp4 wav converter","free mp4 to wav","online mp4 to wav converter","extract audio from video","mp4 audio extractor","video to wav"],"url":"https://toptool.io/mp4-to-wav","runsOn":"client","multiple":false,"batch":false,"input":{"type":"file","extensions":[".mp4"],"mimeTypes":["video/mp4"]},"output":{"type":"file","extension":".wav","mimeType":"audio/wav"},"options":[],"invocation":{"webUi":"https://toptool.io/mp4-to-wav","api":null,"notes":"Currently runs client-side in the user's browser.
