An M4A file is an Apple-developed extension of the existing MP4 file format with some added extra features centred around its audio capability. As this is an Apple-sponsored file format, it has native support for many Apple devices, including iPhones and iPads.

Although it is essentially an extension of MP4, the M4A format allows for improved audio capabilities. One of these is support for the AAC audio format, enabling higher audio compression rates while not sacrificing quality.

Support for M4A is provided by most video and audio editing packages, while playback of M4A files has widespread support amongst not only Apple devices but also Android and Windows too.

MP3 files are a well-known file format for the storage and playback of music and digital audio. The MP3 format has been around for a long time and has become a standard format for music. Despite newer formats arriving, such as AAC, MP3 still remains the primary choice for digital music playback.

It's highly efficient compression methods allow what would otherwise be very large audio data to be compressed down to a fraction of its size with little noticeable difference in quality. The quality, or bit rate, can be specified from 96KB/s (low quality) to 320KB/s (high quality). Naturally, the higher the bit rate, the larger the final MP3 file.

MP3 files are synonymous with digital music and are therefore supported by all major audio and music editing and playback software. Major operating systems and platforms often have built-in support for the playback of MP3 files.
