Open Audio ConverterFrequently Asked Questions
The conversion itself doesn't lose quality, but it doesn't add quality either. An MP3 converted to WAV is a larger file that sounds identical to the MP3. The quality was already reduced when the original MP3 was created.
WAV and FLAC are both lossless (perfect quality). WAV is uncompressed (larger). FLAC is compressed but lossless (smaller, same quality). For lossy, MP3 at high bitrate (320 kbps) or OGG at quality 8+ are both excellent.
