AAC 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.
AAC (Advanced Audio Coding) is the successor to MP3, delivering better sound at the same file size. It is the default for Apple Music, YouTube and most streaming services, and is supported across virtually all modern devices.
AAC plays in Apple Music/iTunes, QuickTime, VLC and on nearly all modern phones, browsers and players.
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.
