2024 Top 10 Best WebM to MP4 Converters for Windows 10/11 & Mac

We are happy to find that Safari finally lines up that experience in macOS Big Sur and iOS 15 after Google Chrome, Firefox, Opera, and IE support WebM video playback. This makes it easier to play the web-optimized and royalty-free WebM video directly in your web browser, when you head over the streaming services like YouTube, Vimeo, Netflix and the like. But you may run into a bit of a snag when you throw the web video to PC, iPhone, Android, HDTV, QuickTime or Windows media Player, unless you convert WebM to a more compatible format like MP4. That's what the article is all about. Stay here and learn why and how to convert WebM to MP4 with high quality.

Part 1. What You Need to Know about WebM to MP4 Conversion?

Prior to converting WebM to MP4, you have to know that both WebM and MP4 are video file extensions or containers for video data.

  • 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.
  • For an MP4 video, it generally consists of video data encoded in HEVC, H.264, or, MPEG4 alongside audio data in AAC or so.

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. You need to rely on third-party video converters (Best video converters in 2024), or online tools to convert (encode) .webm to MP4 file with specific codec as per your needs:

  • MP4 MPEG4: for video playback on the internet.
  • MP4 H.264: Commonly used on Blu-ray Discs & streaming sources. It is probably the most compatible with PC, mobile, media player, etc.
  • MP4 HEVC: 4k, 8k broadcast recording and video playback.

Generally, to get the same file size, the image quality is: HEVC > H.264 > MPEG-4. While to maintain the same image quality, MPEG-4 is half the coding efficiency of H.264 and 1/4 that of HEVC.

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.

Part 4. FAQ about WebM to MP4 Conversion

WebM is a media file format containing VP8/9 video up to full HD 1080P/4320P and Vorbis/Opus audio. It is widely used for HTML5/Chromecast video and natively supported by Mozilla Firefox, Google Chrome, Opera, and Safari on macOS Big Sur. WebM is especially designed for the web, which a more compressed format that takes up less space for the same video than an MP4 file.

2. How do I convert WebM to MP4 on Windows 10?

Windows 10 doesn’t offer the default app right now. But it is simple to save WebM as MP4 on Windows 10, as long as you have the right tools for the job. We recommend using WinX and Handbrake. Both of them are available on Mac and Windows 10. If you don’t want any software download, you can still try the online tools from the post.

3. How to Convert WebM to MP4 in Windows 11?

Right now, VLC 32-bit app makes an entry into Windows 11's microsoft store. You can download it on Windows 11 directly and resort to its file transcoding feature to do the WebM to MP4 converting job on Windows 11. But VLC is rather a media player than a video transcoder, transcoding speed can be relatively slow especially when converting large WebM video to MP4, even though you enable the hardware decoding in VLC. It's better download professional video converter that is compatible with Windows 11 OS and features hardware acceleration tech.

4. How do I convert a .webm file to MP4 on Mac?

Streaming WebM video in Safari can be easier as long as you update to Big Sur. Mac's default QuickTime player cannot handle the downloaded WebM file. Even though it features converting ability, it only exports in MOV format. But you can still try iMovie to import the WebM file and then export the file in .mp4 format.

5. How to convert WebM to MP4 without losing quality?

As is mentioned above, any video encoding involves quality degradation. To turn WebM into MP4 without any loss of quality means the only exchange of file extension without tweaking the video codec or any other information. So if quality matters you most, you can remux WebM to MP4 using software like WinX to do the job.

But the video codec remains the same, in either VP9, VP8, or AV1, which cannot be recognized by most devices. So we still recommend you to choose the WebM video converters listed above and re-encode WebM file for a seamless playback experience.

6. Why Cannot I Import WebM to Adobe?

WebM is not well suited for editing. It is still out of the supported video format list for import. That’s why you encounter "file import failure" error in Premiere Pro. You can fix the error by converting WebM to MP4 or other Adobe accepted format first.
