What happens to your data
Kept
- Constant and variable bitrate MP3 files of any length are supported
- Saved as a raw AAC (ADTS) stream at 192 kbps
Good to know
- A raw .aac file has no room for title, artist or album tags. Choose M4A if you want the tags kept.
- Some players show a slightly wrong length for raw AAC files and cannot jump around in them as smoothly as in M4A.
- Embedded cover art is not carried over. Only the sound is converted.
- Both formats compress with quality loss, so every conversion costs a little quality. Keep your MP3 original.

MP3 vs AAC
MP3
An MP3 file is the most common compressed audio format — small file size, works everywhere, though it loses some audio quality in the process. It's what you'll get from most music downloads, podcasts, and voice recordings.
Used in: Music downloads · Podcasts · Universal playback
AAC
An AAC file is a compressed audio format similar to MP3 but with better sound quality at the same bitrate. It's the standard for streaming audio, YouTube, and most modern devices' default recordings.
Used in: Streaming audio · YouTube · Modern device recordings
