AAC is MP3's better-trained successor: cleaner sound from the same number of bits. Advanced Audio Coding: the default soundtrack of YouTube, iTunes and most MP4 video.
- Born
- 1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia
- Type
- audio ยท lossy
- Typical size
- similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller
- Plays on
- Apple everything, YouTube, Android, modern players; patchy on legacy gear.
- Fun fact
- Every song Apple has sold on iTunes since day one has been AAC, not MP3.
What this AAC converter flips
Two directions, one page. Outbound: turn AAC into MP3, WAV, FLAC, AAC or any format a stubborn app insists on: useful because AAC is weak at older or stubborn hardware that only ever learned MP3. Inbound: turn practically any audio or video file into AAC, which earns its keep at streaming-grade sound at friendly file sizes.
AAC, converted to anything
Questions people ask
What can I convert AAC to?
Any of Flippy's 40+ output formats: MP3, WAV, FLAC, AAC, OGG and more, plus video containers if a platform insists on video.
Will I lose quality working with AAC here?
AAC is a lossy format, so re-encoding trims a little detail each time. Work from the best source you have and convert once: at sensible bitrates the difference stays inaudible.
Is this AAC converter really free?
Yes: free for everyday use with no daily cap, no signup, and your files delete themselves from our servers within an hour. Pro exists for heavy days: bigger files, whole folders at once.
