How to open a WebM file

WebM plays in all current browsers (Chrome, Firefox, Edge) and VLC; older devices or editing software may need it converted to MP4.

What is a WMV file?

WMV (Windows Media Video) is Microsoft’s video format, once common for Windows clips and PowerPoint. It keeps files small but plays poorly outside Windows - Macs, phones and web browsers often can’t open it, so MP4 is the safer choice for sharing.
