Description

WMA is short for Windows Media Audio. Similarly to WMV, it is based on Microsoft’s Advanced Systems Format (ASF). WMA files can contain song metadata, such as song title, artist, and album. By default, WMA files can be played on Windows using Groove Music or the older Windows Media Player.

For greater compatibility, you may wish to convert WMA to MP3 or another audio format.

Description

WebM is a relatively recent video file format for storing high-quality, highly compressed videos with very little quality loss. Because it is also royalty-free, it is frequently used on the web for HTML5 video playback. Its container is based on a Matroska (MKV) profile. It used the VP8 and VP9 technologies for video, and Vorbis and Opus for audio.
