M4A Audio Format M4A Converter
M4A files are an extension of the MP4 container format (MPEG-4 or Moving Picture Experts Group-4). Originally developed by Apple as a competing format to MP3, M4As are specifically used to store audio-only material such as podcasts, music, audiobooks and other auditory entertainment. You can open these files using Apple Music, VideoLAN VLC media player, Microsoft Windows Media Player and others.
M4A files are typically encoded with ALAC (Apple Lossless Audio Codec) or AAC (Advanced Audio Coding), compressing the files to produce smaller file sizes that retain high-quality sound. Due to their reduced file sizes, M4A files are a go-to format for sharing and downloading audio content, especially music downloaded from the Apple iTunes Store. You can play M4A files with most popular media players, including Apple Music, Apple Quicktime, Windows Media Player (if you add the K-Lite Codec Pack), Adobe Audition, and VLC.

MP4 Video Format MP4 Converter
MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.
MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.
