Frequently Asked Questions
Does converting MP3 to AAC improve quality?
No — you can't improve quality by converting between lossy formats. The benefit comes from using AAC as your target format from the start, where it outperforms MP3.
Where is AAC used?
YouTube, Spotify, Apple Music, and most streaming platforms use AAC. It's also the default codec for iPhone, iPad, and modern Android devices.
What's the difference between AAC and M4A?
AAC is the codec (compression algorithm). M4A is the file container that typically holds AAC audio. They're closely related.
Should I switch from MP3 to AAC?
For new audio, yes — AAC is better. For existing MP3 libraries, the quality gain from transcoding is minimal and may introduce artifacts.
