Converting M4A to WAV is a common task when you need lossless, perfect quality. M4A is an MPEG-4 audio container, usually holding AAC. It offers better quality than MP3 at the same bitrate and is the default for iTunes, Apple Music and voice memos, but plays less universally than MP3. WAV, on the other hand, gives you lossless, perfect quality and ideal for editing. ZeroUpload performs this conversion entirely inside your browser, so your M4A file is never uploaded to a server.
