Format description
MP4 (short for MPEG-4 Part 14) files store multimedia - video, audio and subtitles. Websites frequently use them for displaying videos because the MP4 format is universally supported. However, newer video formats, such as WebM, produce smaller file sizes with almost no quality loss. Therefore, you can free up storage by converting your videos to WebM.

Format 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.
Common questions about converting MP4 to MP3
Can I convert MP4 to MP3 in bulk?
