Uncompressed Audio Converter

About Uncompressed Audio Converter

WAV stores audio completely uncompressed — every sample exactly as decoded, with no lossy encoding applied at all. This makes it the format of choice whenever a downstream tool (an audio editor, a voice analysis pipeline, certain professional software) specifically expects lossless input rather than a compressed format like MP3. This tool converts any audio file your browser's FFmpeg build can decode into WAV.

A real FFmpeg build compiled to WebAssembly handles the decoding and re-encoding entirely inside your browser, outputting standard 16-bit PCM audio — the most broadly compatible WAV variant, readable by essentially any software that accepts WAV files at all.

The trade-off for WAV's lossless guarantee is file size: since nothing is compressed, a WAV file is typically many times larger than an equivalent MP3 or OGG file of the same audio — this is expected and inherent to the format, not something a conversion setting can avoid.

Converting a file that started as a lossy format (MP3, AAC) to WAV doesn't add back any quality that was already lost during the original lossy encoding — WAV simply avoids introducing further loss beyond that point, rather than reversing prior compression.

How it works

1. Upload your audio file. Any format your browser's FFmpeg build can decode.
2. Conversion runs locally. Audio is decoded and re-encoded as uncompressed WAV.
3. Download the WAV. Lossless 16-bit PCM audio, ready for further processing.
