MP3 Audio Format MP3 Converter
MP3 is the most common format for storing and playing digital music. It’s short for ‘MPEG-1 Audio Layer 3’, and it was developed in the early 1990s as a way of compressing audio to create smaller files that could be easily shared and stored without losing too much sound quality.
MP3 is a universal format maintained by the International Office for Standardization (ISO). MP3 tracks will play on almost any device and with most media players, including Windows Media Player and Apple Music. Digital music took off in the 1990s and 2000s, and many users used media players to ‘rip’ CDs, or download tracks from sites like Napster, turning MP3 into the most common audio format. Because MP3 uses ‘lossy’ compression that can’t be reversed, some music listeners prefer to use other formats such as FLAC, even if the file sizes are bigger.

M4A Audio Format M4A Converter
An M4A file format is also called an MPEG-4 audio file, and is an audio file saved in the MPEG-4 standard. It was developed by Apple, largely as a result of the popularity of the MP3 file. An M4A file is the go-to audio format for compressed audio, due to the creation and popularity of iTunes.
M4A files tend to be encoded using an AAC codec and are small in size because they have been compressed - often providing a smaller file-size footprint than an MP3 file format, while mirroring, if not improving, the quality of an MP3 file. As more and more music was consumed on the go via devices such as iPods and smartphones, the need for small file sizes became greater, which is why an M4A file has grown in popularity and importance.
One downside of an M4A file, especially when compared to an MP3 format, is that it can only be opened by iTunes or Windows Media Player version 12 and later. By comparison, an MP3 file is universally supported.
