Audio to WAV Converter

No. The file is decoded and converted locally in your browser using the Web Audio API. It is never sent to a server, so private recordings and unreleased tracks stay private.

Any format your browser can decode, which typically includes MP3, OGG, M4A, AAC, FLAC, WebM and WAV itself. If a file cannot be decoded, an error message explains that clearly instead of failing silently.

WAV is an uncompressed PCM format that browsers can write natively without any external library, so the conversion is instant and lossless. Encoding to compressed formats like MP3 would need a large third-party encoder, which this tool deliberately avoids.

Sample rate and channels let you resample the audio (for example down to 16000 Hz mono for voice) or upmix/downmix between mono and stereo. Bit depth controls how each sample is stored: 16-bit PCM is the standard, widely compatible choice, 32-bit float preserves the most precision, and 8-bit PCM produces the smallest, lowest-quality file.

Decoding to WAV at 16-bit or 32-bit float and keeping the original sample rate and channel count preserves the full quality of the decoded audio. Quality can only be reduced if you deliberately choose a lower sample rate, fewer channels, or 8-bit depth.

Files up to 150 MB are supported. Since decoding and encoding happen in your browser's memory, very large or very long files may take longer or use more memory depending on your device.

Browsers decode audio internally to their audio output device's sample rate, commonly 44100 Hz or 48000 Hz, before this tool ever receives the data. The Decoded sample rate shown reflects what your browser produced, which can differ from the source file's originally encoded rate. Keep original preserves that decoded audio exactly, with no further resampling. If you need a specific rate, choose it from the Sample rate dropdown.
