Convert ASF files for playback, extraction or compatibility
ASF is a Microsoft streaming media container, so people often convert it when a player, editor or upload service does not handle it well. Converting ASF can make video easier to play on phones, browsers and media apps, or make it easier to extract audio from a recording when you only need the sound.
