About WebM files
WebM is an open video format made for the web. Screen recorders, browser-based tools and many websites use it, with VP8, VP9 or AV1 video and Opus or Vorbis sound inside.
iPhones, QuickTime and many video editors still struggle with WebM. These converters turn WebM into MP4 or extract its sound as MP3, and make a WebM from an MP4 for your own website.
