WebM is a container rather than a single video codec. WebM files commonly use VP8, VP9 or AV1 for video and Vorbis or Opus for audio.
Modern browsers provide strong WebM support, making the format useful for websites, embedded video and web applications. Compatibility in older desktop software or hardware can be less universal than MP4.
WebM is closely associated with open web media, while MP4 has especially broad support across consumer devices and editing software. The better choice depends on where the file needs to play and which codecs the target platform accepts.
For WebM, MimiFile currently offers 2 conversions to other formats and 1 conversion from another format.
