How to convert to WAV
WAV is an uncompressed audio format developed by Microsoft and IBM. It stores raw PCM audio data with no compression, which makes it the preferred format for professional audio editing, music production, and any workflow where audio quality must be preserved without any lossy encoding. WAV files are larger than MP3 or AAC, but they are the gold standard for master recordings and audio processing.
BoltConverter converts audio files to WAV in your browser using WebAssembly. MP3, AAC, OGG, FLAC, M4A, and other audio formats can be converted to WAV. The conversion runs locally and your audio files are never uploaded to a server.

Frequently asked questions
Why use WAV instead of MP3?
WAV is uncompressed and lossless, making it the right choice for audio editing, mixing, and mastering. MP3 uses lossy compression that degrades each time you re-encode. Use WAV for production, MP3 for distribution.
Will converting from MP3 to WAV improve the quality?
No. Converting from a lossy format like MP3 to WAV does not restore compressed-away quality. The WAV file will be larger but will not sound better than the MP3. Start with lossless source material for best results.
What sample rate does the output WAV use?
The output WAV uses the sample rate of the source audio file. Common values are 44100 Hz (CD quality) and 48000 Hz (broadcast standard).
Are my files kept private?
Yes. The conversion runs entirely in your browser using WebAssembly. Your audio files are never uploaded to any server.
What formats can I convert to WAV?
MP3, AAC, M4A, OGG, FLAC, and most other common audio formats are supported. The exact list depends on your browser's audio decoding capabilities.
