Audio editors, samplers, transcription tools, and older software often demand uncompressed WAV input — but your recordings come out as MP3, M4A, or WebM. Our free Audio to WAV Converter decodes any audio format your browser supports and rewrites it as standard PCM WAV, entirely on your device, in seconds.
The conversion uses the Web Audio API to decode your file to raw samples and then packages those samples into a WAV container with no additional lossy step. The result is maximum compatibility: WAV files open in every DAW, video editor, and audio utility ever made.
Because nothing is uploaded, the converter works offline once the page is loaded and is safe for confidential recordings. It pairs naturally with the rest of our audio suite: capture takes with the Voice Recorder, rip soundtracks with the Video Audio Extractor, and cut the converted WAV down to size with the Audio Trimmer.
