Compare video formats for sharing, archiving and playback

Choose a format around the destination and the streams you need to keep.

ContainerExtensionTypical contextWhat to check
MP4.mp4A broadly used container. H.264 video with AAC audio is a practical starting point for sharing.Check the actual codec and profile; MP4 can also hold less widely supported streams.
WebM.webmOften used for web delivery with VP8, VP9 or AV1 video and Vorbis or Opus audio.Older devices may have limited hardware decoding.
MKV.mkvA flexible container that can hold multiple tracks and subtitles.The player must support both the container and each selected stream.
MOV.movCommon in camera and editing workflows.The codec may be H.264, HEVC, ProRes or another format; large editing files are not ideal for every phone.
AVI.aviA legacy container still found in older video collections.An AVI extension alone says very little about whether a modern phone can decode it.
M4V.m4vCommonly associated with MPEG-4 video files.Protected files require an authorized playback path. Renaming does not remove protection.
3GP.3gpA container associated with mobile video and older handsets.Check the codec, frame size and quality before converting or archiving.

Three decisions before conversion

  1. For sharing: ask which player or platform receives the file.
  2. For archiving: retain your original and any license or attribution information.
  3. For playback: inspect codecs and test sound, seeking and subtitles.
