What happens when you convert AAC to OGG
| Compression | Lossy → Lossy |
|---|---|
| Size per minute | AAC ≈ 1.4 MB → OGG ≈ 1.4 MB at 192 kbps |
| Quality | Re-encoded once more; at 192 kbps or higher the extra loss is very hard to hear |
| Tags | Title, artist and album tags are copied when the target format supports them |
| Opens in | browsers, Android, VLC and games; iPhone apps and many car stereos do not |
Sizes are typical values; your files will vary with content and settings.

Why convert AAC to OGG?
Raw AAC files come from some phone recorders, internet radio streams and audio pulled out of videos. Raw .aac files have no chapter or cover-art support and some players skip them. Choose OGG Vorbis for game engines such as Unity and Godot, and for open-source software.
Frequently asked questions
Will the OGG lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
Will the OGG be smaller than the AAC?
About the same: a minute of audio takes about 1.4 MB as AAC and about 1.4 MB as OGG at 192 kbps. Lower the bitrate to shrink it further; 128 kbps is plenty for speech.
