Converting M4A to OGG is a common task when you need better quality than mp3 at equal size. 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. OGG, on the other hand, gives you better quality than mp3 at equal size and free and open. ZeroUpload performs this conversion entirely inside your browser, so your M4A file is never uploaded to a server.
