WAV files are uncompressed, meaning they offer the highest audio quality but take up a massive amount of storage space. Converting a WAV file to MP3 reduces its file size significantly (often up to 90%), making it much easier to email, upload to websites, or store on mobile devices.
Because MP3 is a compressed format, some data is technically discarded to reduce the file size. However, our encoder is highly optimized. For everyday listening, podcasts, and standard web sharing, the quality difference is virtually unnoticeable to the human ear.
