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.

Description

MP3 is a commonly used audio format. The audio data is compressed inside the file, which is why MP3 files take up less space than WAV, for example. Even though the audio is compressed, the quality is still good enough for most personal use cases.
