M4A is an extension for the MPEG-4 file format that can contain audio streams. The format is used to store digital audio with AAC (Advanced Audio Coding) or ALAC (Apple Lossless Audio Codec) compression techniques. While M4A was previously used by Apple, it has now gained popularity on other platforms too. You can use it to contain audio files with metadata and compress even a large chunk of audio in limited storage.

MP3 is the most popular coding format to contain and store digital audio files across various systems. It is an open format that was first released in 1991. Just like MP4, MP3 is also a lossy format, but it is vastly used on different tools and devices due to its universal compatibility.

There are plenty of online applications and desktop software that you can use for converting files to M4A for free.

You can simply launch iTunes and go to its Preferences to change its Import Settings. Later, you can load the MP3 file and go to File > Convert to convert MP3 to M4A on iTunes.

By following ALE/ALAC (lossless) codec, the audio quality of the file won’t be lost while the AAC (lossy) codec might end up compromising its quality.
