M4A and OGG both use lossy compression. Re-encoding may introduce a small additional quality loss, especially in audio that has already been compressed several times.
M4A is an audio format that usually holds AAC-encoded sound in an MP4 container. It is Apple’s standard for music downloads and voice memos, offering great quality at small sizes and playing natively across the Apple ecosystem.
M4A plays in Apple Music/iTunes, QuickTime, VLC and most modern media players; on older devices, convert it to MP3.
OGG is a free, open audio format (usually Vorbis or Opus) that delivers great sound at small sizes without licensing fees. It is popular in games, on the web and with open-source software, but some devices need it converted to MP3 first.
OGG plays in VLC, Firefox, Chrome and most media players; on iPhones and older devices, convert it to MP3 or M4A.
