Notes

  • From iOS 11, iPhone 7 and later models record video in HEVC (H.265) by default, which some computers and websites cannot open.
  • If the video in a MOV file is already H.264, it is only repackaged as MP4 without re-encoding. This is quick and the quality is unchanged.
  • MP4 with H.264 video and AAC audio opens on almost every system and website. If you are unsure, please choose this option.
  • “Original codec” does not re-encode, so it is the fastest and the quality is unchanged. However, HEVC (H.265) videos do not open on some computers and websites.
  • When an HDR video is re-encoded, it is saved in standard dynamic range and its colours may look paler.
  • Processing time depends on your device and the length of the file, and progress is shown on the page. Processing takes longer on a phone, so please keep this page in the foreground and do not lock the screen.

Questions and answers

Can an iPhone record in H.264 instead?
Yes. On the iPhone, go to Settings > Camera > Formats and choose Most Compatible. New videos will then use H.264.
Is quality lost in conversion?
Not when a video is only repackaged. When re-encoding is needed, a high quality setting is used, and the file size may differ from the original.
Is the audio kept?
Yes. The audio is converted as well: to AAC for MP4 and to Opus for WebM.
