What changes when you convert AAC to OGG
Both AAC and OGG are lossy, so this conversion decodes AAC-LC and re-encodes it as Vorbis. That second encode adds its own loss on top of the first. Choosing a higher bitrate, up to 320 kbps, keeps the damage small enough to be inaudible in most material.
Be aware that you are narrowing playback: AAC is natively supported on 5 platforms where OGG is not. Convert this way when you need the format specifically, not for portability.
The two formats are aimed at different jobs. AAC is typically used for streaming services, mobile playback, broadcast, while OGG is the usual pick for game audio, open-source projects, web delivery. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: ID3v2 (limited in ADTS) in the source becomes Vorbis comments in the result. Standard fields map cleanly; niche custom tags often do not.
About AAC to OGG Conversion
This page converts AAC files, stored in the ADTS / raw AAC container since 1997, into OGG, which uses Ogg and dates from 2000. The differences between the two containers decide what changes in the result.
AAC comes from MPEG / Fraunhofer IIS and dates to 1997. It carries AAC-LC, HE-AAC, which is what determines the quality ceiling of anything you convert out of it.
OGG was introduced by Xiph.Org Foundation in 2000. It carries Vorbis and has native playback on 1 of six platform categories, which is the practical reason to choose it as a target.
