To say even more:

What is WebM?


WebM is an open source video file format made for online video streaming. WebM structure replicates the MKV (Matroska) media container. WebM video file steams use VP8 or VP9 video codecs. Both VP8 and VP9 are open and royalty-free video compression technologies owned by Google. WebM audio streams are compressed with the Vorbis (OGG) or Opus audio codecs.

Which is better MP4 or WebM?


There is no ultimate answer to this question. WebM is a rather new format which appeared only 8 years ago. MP4 is an old well-known media extension supported by almost all modern handheld and desktop devices. Speaking about playback in various browsers, MP4s play fine in all browsers (Chrome, Mozilla Firefox, Opera, Internet Explorer, Microsoft Edge, etc). However, you might have issues with WebM video player in Microsoft Internet Explorer.

Why is encoding time for WebM so long?


It’s a myth. Our MP4 to WebM software is quick and easy. It doesn’t take a lot of time to convert & encode to WebM. The program processes an average 5 minute MP4 video for one minute. Is it long?

How to play WebM files?


To playback WebM videos on a webpage, feel free to use the web video player created by Freemake. See step #5 above for details.
To play WebM files offline on Windows, Macintosh or Linux, use any free cross-platform video/audio player like VLC. It’s free and supports WebM format natively.

How to convert MP4 to WebM with Handbrake?


Handbrake is a popular conversion tool for Mac OS. To convert MP4 files with it, install the software on your computer, then select Media > Convert/save from the menu. Click the "Add" button and upload the video file you want to convert. Next, press the "Convert/Save" button and in the profiles dropdown menu choose "Video - VP80 + Vorbis (Webm)". Start the conversion.

As you can see, the process isn't so straightforward as the steps above. So for Windows OS we recommend you using Freemake software.
