About AAC to MP3 conversion
AAC is used by Apple Music, YouTube, and many phones. Convert it to MP3 for a car stereo, an older player, or an app that does not read AAC. The conversion runs on your device.
Both formats are lossy. Re-encoding costs a little quality, so use 192 kbps or higher.
Frequently asked questions
Is AAC the same as M4A?
M4A is a container that usually holds AAC audio. If your file ends in .m4a, try the M4A to MP3 converter instead.
Does iTunes use AAC?
Yes. Songs bought or downloaded from Apple Music are AAC, often inside an M4A file.
Is my AAC file uploaded?
No. The converter runs in your browser with FFmpeg WebAssembly. The file never leaves your device.
