About the formats

What is M4A?

M4A is an MPEG-4 file that contains only audio; the extension simply tells players there is no video inside. The sound is usually compressed with AAC (lossy) or ALAC, Apple Lossless. It was popularised by iTunes and is the format of iTunes Store purchases, Apple voice memos and many audiobooks and podcasts.

Use M4A for music and recordings in the Apple ecosystem, where it offers better quality than MP3 at the same bitrate. If you need to play the file on older players or systems with limited support, MP3 remains the most compatible option.

What is OGG?

Ogg is an open, patent-free container format maintained by the Xiph.Org Foundation. An .ogg or .oga audio file usually contains sound compressed with the lossy Vorbis codec, though it can also hold Opus or FLAC. Vorbis offers good quality at moderate bitrates and is used in many video games and by some streaming services.

Use OGG when you want an open, royalty-free format for games, open-source software or web audio in browsers that support it. For maximum compatibility with Apple devices and car stereos, MP3 or AAC are the safer choice.
