What is a MP3 file?
MP3 is one of the most iconic and widely used audio formats in the world. It uses lossy compression to significantly reduce file sizes while maintaining acceptable sound quality. MP3 revolutionized digital music distribution and became the standard format for portable media players and online music sharing.
Thanks to its balance of quality and size, MP3 remains highly relevant for casual listening, streaming, and downloading music. Nearly every media player and device supports it natively.
How to open MP3 files
MP3 files can be opened with virtually any media player: Windows Media Player, iTunes, VLC, Winamp, and countless mobile apps all support the format.
You can also convert MP3 to other formats like AAC or WAV quickly using AnyConv online.

What is a M4R file?
M4R is another extension of the M4A format, used specifically for iPhone ringtones. It contains AAC-encoded audio and is designed to be easily imported into iOS devices via iTunes. In most cases, M4R files are short clips extracted from longer M4A or MP3 songs.
Despite being almost identical to M4A in structure, the M4R extension helps iTunes and iPhones recognize the file as a ringtone rather than music or podcast content.
How to open M4R files
M4R files are used for iPhone ringtones and can be played or transferred using iTunes. On most systems, VLC and QuickTime can also open them directly.
To create a ringtone or convert M4R to another format, AnyConv is a convenient online tool.
