What is an M4R (Apple iPhone Ringtone) file?

Apple iPhone Ringtone (M4R) is the file format Apple uses to store ringtones on iPhones. The maximum length of an M4R file is 40 seconds. The only difference between M4R and MPEG 4 Audio (M4A) is the file extension, which lets an iPhone know M4R is a ringtone instead of a song.

How to open an M4R file?

As a format deployed by Apple for iPhone ringtones, M4R files open on iTunes by default.

Alternatively, Apple iOS is another good choice for opening M4R files. To create a custom ringtone, simply save an M4A file as an M4R file, and then import it into the iPhone.

What is a WEBM (WebM) file?

WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.

How to open a WEBM file?

VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.

Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.
