So whether you are on the hunt for a way to view WebM file on Windows 10/11, play WebM on iPhone or iPad, or import it to Premiere Pro, it's highly recommended to convert Webm video to MP4 H.264 to eliminate any playback or editing incompatibilities. While to maintain the same image quality, MPEG-4 is half the coding efficiency of H.264 and 1/4 that of HEVC. Generally, to get the same file size, the image quality is: HEVC > H.264 > MPEG-4.

We have to make it clear that mere file extension change from WebM to MP4 cannot solve the WebM video playback problem at all, since the codec or other data information isn’t converted at all. For an MP4 video, it generally consists of video data encoded in HEVC, H.264, or, MPEG4 alongside audio data in AAC or so.

For a WebM video, it normally includes video streams compressed with either VP8, VP9 or even the newest standards AV1, and audio streams compressed with Vorbis or Opus audio codec.Prior to converting WebM to MP4, you have to know that both WebM and MP4 are video file extensions or containers for video data.
