What to know before converting

Use this page when a video will not play, edit or upload because of its format. MP4 is the safest target for phones, browsers and social uploads.

  • 品質. Converting can lower the quality a little when the picture is compressed again, and it never adds resolution or detail the source did not have.
  • Your rights. Convert only files you own or have permission to use.
