What is a .M4A file?
Everything worth knowing about MPEG-4 Audio File.
An M4A file is an MPEG-4 audio file, the audio-only version of an MP4, usually with AAC (lossy) or ALAC (Apple Lossless) audio. It plays natively on Windows 11, macOS, iPhone, and Android without any extra software. The most common task is converting M4A to MP3 for older devices that only support MP3.

Why does a file show audio but no picture (or not play at all)?
A container like MP4, MOV or MKV can hold many codecs. If your browser lacks the codec inside (for example H.265 or AC-3 audio), the player tells you and offers the Media Converter, which can turn it into a format that plays everywhere.
Can I play AVI, WMV, FLV or MKV files?
Browsers don't play these old or exotic containers natively. Open them in the Media Converter: it inspects every track and converts the file to MP4, WEBM or MP3.
