# What is a WAV file?
WAV is an uncompressed audio format that retains original, studio-like sound quality. Because it is lossless, files are large, making it the standard for professional audio editing rather than streaming. WAV is an uncompressed, lossless audio format preferred by studio producers for its pristine sound quality. The downside? A simple 3-minute song can easily take up 50 MB of storage.
# Why convert to MP3?
MP3 is the world's most popular audio format. It uses lossy data compression to significantly reduce file size while maintaining acceptable audio quality, making it ideal for music storage and streaming. Converting WAV to MP3 shrinks the file size by up to 90%, making it small enough to email, upload to websites, or store thousands of songs on your phone. Our 320 kbps encoder ensures the human ear can't tell the difference.
