Converting WAV to M4A is a common task when you need better quality than mp3 per byte. 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. M4A, on the other hand, gives you better quality than mp3 per byte and efficient compression. ZeroUpload performs this conversion entirely inside your browser, so your WAV file is never uploaded to a server.
