Turn your AAC file into an uncompressed WAV — the format most audio editors, mixing software, and older devices expect. It's converted right on your own device, so the audio file itself is never sent anywhere. Select the AAC or M4A file you'd like to convert. It never leaves your device at any point in the process. Your browser decodes the compressed AAC audio and writes it out as raw WAV data. Nothing is sent to a server. Download your new WAV file — uncompressed and ready for editing or any software that needs raw audio. Yes, there's no limit on conversions and no signup required. No. Conversion happens entirely in your browser; your file is never uploaded to a server. Files are exported as standard 16-bit PCM WAV, at the same sample rate and channel count as your original AAC file. Most .aac and .m4a files decode directly in current versions of Chrome, Firefox, Edge, and Safari. If a file won't convert, try re-saving it as .m4a first or updating your browser.AAC to WAV Converter
