Opening m4p files

Have a problem opening a .m4p file? We collect information about file formats and can explain what m4p files are. Additionally we recommend software suitable for opening or converting such files.

What is the .M4P file type?

The .m4p file extension stands for 'MPEG-4 Audio, Protected' and represents AAC-encoded MPEG-4 audio files protected with the Apple's proprietary Fairplay Digital Rights Management (DRM) technology. M4P files contain DRM-protected music purchased from the iTunes Store. Unprotected MPEG-4 audio files would have the .m4a or .m4b extension.

The M4P format mainly uses the lossy Advanced Audio Codec (AAC) compression that offers better sound quality and generally smaller file sizes than MPEG Layer III (MP3) at the same bitrate.
