MP3
MPEG-1 Audio Layer III
MP3 is the most compatible audio format there is — car stereos, gym equipment, DAWs, phones from 2003. It is lossy and no longer the most efficient codec, but "it plays everywhere" outranks efficiency for most people converting to it.

Opening a .mp3 file
If you landed here because something handed you a .mp3 file and
nothing on your machine will open it, converting it to a format you already have a
reader for is usually faster than installing new software. Every conversion above runs
in this browser — the file is not uploaded, so it works on a locked-down work machine
and on a file you are not allowed to send anywhere.
