Convert MP3 to AAC
Re-encode MP3 to AAC for Apple devices and modern streaming, where AAC sounds better per kilobit. Because both are lossy, this is a generational re-encode — keep the bitrate equal or higher.
Why convert MP3 to AAC?
- AAC delivers better quality than MP3 at the same bitrate, ideal for mobile
- Native format for iPhone, iTunes, and most streaming platforms
- Set the output bitrate to match or exceed the source to limit added loss
- Lossy → lossy: re-encoding always sheds a little quality, so avoid repeated round-trips
