About M4A files
M4A is AAC (or ALAC) audio in an MPEG-4 container. Apple Music, iTunes, voice memos and many podcasts use it.
All major browsers play AAC in M4A. Apple Lossless (ALAC) plays in Safari only.
What you can do here
- Play the file with your browser’s player
- See duration, codec, bitrate and sample rate
- Read tags like title, artist, album and cover art
Limitations
- Whether a file plays depends on the codecs your browser supports.
Privacy
The file is read by your browser and stays on your device. Open Online has no server that could receive it, and nothing is stored once you close the tab. Privacy policy
