How to convert AAC to OGG
- Add your .AAC file - drop it in the box above or click to browse.
- Convert it to .OGG in a few seconds.
- Download your new .OGG file.
What to expect
- Both AAC and OGG Vorbis are lossy formats; converting re-compresses already-compressed audio, so the resulting
.oggwill be slightly worse than the original.aacsource. - AAC is generally more efficient than Vorbis at the same bitrate, meaning re-encoding at equal bitrate does not recover the original quality.
- Files with a
.m4aextension are AAC audio inside an MP4 container - all tools listed handle.m4aand.aacidentically.
Frequently asked questions
Will converting AAC to OGG improve audio quality?
No - OGG Vorbis is patent-free but not more capable than AAC, and starting from a lossy source means quality can only stay the same or get slightly worse.
Can I convert a `.m4a` file to OGG the same way?
Yes - VLC, Audacity, fre:ac, and FFmpeg all treat
.m4a (AAC wrapped in an MP4 container) identically to a raw .aac file.What Vorbis quality setting should I use with FFmpeg?
Use
-q:a 4 (~128 kbps) for typical sources; use -q:a 6 (~192 kbps) if your AAC was encoded at a higher bitrate.Does OGG always mean Vorbis audio?
Almost always - the
.ogg extension conventionally means Vorbis; Opus audio (a newer codec) is more commonly saved as .opus.Programs that convert AAC: Helium Music Manager · Aimersoft DRM Media Converter for Windows · Any Audio Converter · Audacity · FormatFactory · fre:ac · Free Mp3 Wma Converter · Freemake Audio Converter
