What is an M3U8 file?

An M3U8 file is a playlist file used by various audio and video playback programs. It contains a path or URL to a media file or folder of media files, along with information about the playlist. M3U8 files use the same formatting as .M3U files, except the text stored in the files uses UTF-8 character encoding.

M3U8 files are often used for storing playlists that have song names in different languages. They may also contain references to online files for an Internet radio station.

Some M3U files may already use UTF-8 character encoding. However, M3U files may also use other character encoding standards. Therefore, the M3U8 extension is used to explicitly state that UTF-8 character encoding is used.

NOTE: On rare occasions, M3U8 files may be saved with the .M3UP extension.

How to open an M3U8 file

You can open an M3U8 file and play the playlist it contains in many media players, including Microsoft Windows Media Player (Windows) and VideoLAN VLC media player (cross-platform).

You can also open your M3U8 file in any text editor, such as Microsoft Notepad (Windows) or Apple TextEdit (Mac), to view the text it contains.
