Converting WAV to MP3 is a common task when you need plays everywhere. WAV is an uncompressed, lossless audio format that stores raw sound exactly. The quality is perfect and editing-friendly, but the files are large, so WAV is common for production and converting to MP3 for sharing. MP3, on the other hand, gives you plays everywhere and small files. ZeroUpload performs this conversion entirely inside your browser, so your WAV file is never uploaded to a server.
