What is an M4A file? M4A is an extension for an audio file encoded with AAC (Advanced Audio Coding) or ALAC (Apple Lossless Audio Codec). It is a common extension for audio imported from CDs using iTunes. M4A files sound better and have a smaller size compared with MP3, which is why you might want to convert your MP3s to this format. This can be easily done with Movavi’s MP3-to-M4A converter. Read this guide to learn how to convert MP3 to M4A with Movavi’s software.
