An MP4 file can carry media encoded with different codecs. H.264/AVC and H.265/HEVC are common video codecs, while AAC is frequently used for audio. Playback compatibility therefore depends partly on the codecs inside the MP4 file.
MP4 is supported by most modern browsers, phones, televisions, media players and video editors. Its broad ecosystem support is one of the main reasons it is commonly chosen for sharing and delivery.
Both formats are multimedia containers. MP4 generally prioritises broad device and software compatibility, while WebM was designed around web delivery and commonly uses codecs such as VP8, VP9 or AV1 with Vorbis or Opus audio.
