About AAC
AAC is the lossy format used by Apple Music and YouTube. At the same bitrate it generally sounds better than MP3.
Questions
Is the AAC converter free?
Yes, it is free with no sign-up and no watermark. There is no cap on how many files you can convert, and nothing to install.
Do my files get uploaded to a server?
No. The conversion runs entirely in your browser using code that loads onto your device, so the file is read, converted, and downloaded locally. It never reaches us or anyone else.
Which format should I convert my AAC to?
It depends on what you need. For wide compatibility choose a mainstream format; for the smallest file choose a modern, efficient one. Each conversion page explains the trade-off.
