WAV is uncompressed PCM audio: the format audio editors, samplers, DAWs, and phone systems ask for when they want raw, dependable input. This converter turns any audio file — or the sound of a video — into a standard WAV file locally in your browser.
People typically need it to prepare clips for editing software that dislikes compressed input, to feed IVR or telephony systems that require WAV, or to hand a sound designer a clean file. Because WAV is uncompressed, expect the output to be considerably larger than an MP3 of the same clip.
Everything runs locally: the file is decoded and rewritten as WAV by in-browser WebAssembly, with nothing transmitted to any server.
WAV stores uncompressed samples, so a 4 MB MP3 can easily become a 40 MB WAV. That size is exactly what editing tools want: no decoding artifacts and instant seeking.
Yes. Drop in any common video (MP4, MOV, WebM, MKV and more) and its audio track is extracted and converted automatically; the video stream is simply discarded.
No. The conversion is performed by a WebAssembly build of FFmpeg running inside your browser tab. The file never leaves your device, and closing the tab removes it from memory.
