Most free converters add watermarks or throttle quality. AudioUtils does neither. You get the same output quality whether free or paid.
Free users get 5 conversions per day. That covers most casual needs. The conversion engine is identical to Pro. Same speed, same quality, same privacy.
Your files stay on your machine. Nothing is uploaded. Both AAC and MP3 are lossy formats. Each re-encode can degrade quality slightly. Convert once and keep the result.
Frequently Asked Questions
Is AAC better than MP3?
At the same bitrate, AAC generally sounds better than MP3. It's a newer, more efficient codec. But MP3 has broader device support.
Will I lose quality converting AAC to MP3?
Some quality loss is inevitable when transcoding between lossy formats. Use a high bitrate (256-320kbps) to minimize the impact.
What's the difference between AAC and M4A?
AAC is the codec (compression method). M4A is the container format that usually holds AAC audio. They're closely related — M4A files typically contain AAC-encoded audio.
When should I keep AAC instead of converting?
If your devices support AAC, keep it — it's better quality. Only convert to MP3 when you need maximum compatibility.
